The first and most complete application of the Garmin store for windsurfing, kitesurfing, hydrofoiling, kitefoiling, wing surfing, wing foiling and snowkiting.
Thirteen complete screens are available:
- screen 1: main screen (current, average, and max speeds, heading, wind axis + efficiency angle upwind / downwind, altitude, elapsed distance, accelerometer, chronometer, as well as the count of the calculation of the 10s. and 30s. runs
- screen 2: the accelerometer, last and best 10s. run, last and best 30s.run, average and max speeds, the heart rate and the number of jibes realized
- screen 3: rather dedicated to kitesurfing, 3 arcs of jumps (the best ever, the best of the session, the last realized), as well as the corresponding values for the best of the session and the last jump made, a horizontal colored bar representing the efficiency angle upwind (0 to -90 °) or downwind (0 to 90 °), green = ideal angle, orange = average angle, red = angle too close.
- screen 4: screen for more technical navigation conditions, showing the wind efficiency, and the current speed as well as its gauge in relation to the maximum speed of the session plus the average speed cursor
- screen 5: compass with wind efficiency
- screen 6: virtual partner + average speeds over 500-meter runs
- screen 7: topo map representing your location + wind efficiency display (for models equipped with maps feature)
- screen 8: graph representing the efficiency of your speed in each angle of navigation compared to the wind
- statistical screen 9: the best of all scores, all sessions combined
- statistical screen 10: the total of some data + stats, all sessions combined
- statistical screen 11: your skills level
- end session screens (12 and 13): display a summary of the main data obtained during the session
Jumps are actually triggered and calculated either by the accelerometer or the barometric altitude (option to select in the options menu of the app).
In the FIT file, the following data are saved:
- GPS track of the session
- speed, in km / h or knots, if this speed is equal or higher than the chosen planing speed
- acceleration, in g
- the efficiency of the upwind and downwind angle
- the size of the sails / wings used during the session
- the efficiency score index of your speed / angles for each navigation angle
•• as lap:
- the height + airtime for each jump, in meters or feet
- the jibe score for each jibe done
•• summary data:
- the height and airtime for the best jump of the session (summary)
- the best speed on a 10s. run
- the best speed on a 30s. run
- the best average speed and best chrono over 15 customizable distances (only for 1024 Kb devices)
- the best average speed on an Alpha500 challenge (if this data exists)
- the average jibe score for all the session
- the overall score for speed efficiency in relation to navigation angles (only for 1024 Kb devices)
- your own feeling of the session (score ranking)
If you have a Strava account (linked to your Garmin account), all of these FIT data will also be automatically pushed to it.
Note: all the options set in the menu are permanently saved into the watch so, no need to configure them each time you launch the application.
Given its complexity and time spent developing, the price of this application is set to 16 US dollars, or 20 to 25 times cheaper than a North PIQ or WOO 3.0 sensor so, it makes sense to have this kind of application on Garmin devices.
For further detailed explanations, you can consult the detailed images below.
Despite all the care taken in this application, it could remain some hidden bugs, or possible malfunctions. Therefore, thank you to contact me directly by email to inform me rather than posting bad comments on the site, I will then do what is necessary to fix the issue as soon as possible. Thank you in advance.
My warmest thanks to Giuseppe for all the tests he has done in the Neapolitan Sea, his valuable advice on kitesurfing as well as his wise and relevant suggestions, as well as Stijn for the few tests done in Spain. Thanks to them.
Currently unemployed, I develop applications for the Garmin community to stay active and "in the wind".
The paid version can be unlocked via my Paypal account (see the link above), with the possibility to pay with credit cards too.
Don't forget to mention the name of the application, JMG-APP Wind-Kite Surfing, your gender (0= female, 1 = male), your birth year and your height mentioned in your Garmin profile, in your PayPal comment.
Please, feel free to enjoy !
there are 2 major versions of this application, one for low-RAM models (LOW version), and another for models with higher memory capacity (HIGH version).
- LOW version -> Bravo + Titanium D2, ForeAthlete 735XTJ, Forerunner 230, 235, 630 and 735XT, Forerunner 920XT, Fenix 3 + Quatix + Tactix, Fenix 3HR, Vivoactive + Vivo HR. The features of this version are described on the app's explanation page on the Garmin Connect app website
- HIGH version -> all other watch models. This category is itself divided into 2 subgroups, one for models with 124 KB of memory, and the other for models with 1024 KB of memory.
Version HIGH 124 Ko
Version HIGH 1024 Ko

Main differences between the 2 versions
- Simplified Race Mode:
- 2 jump calculation algorithms
- no management / monitoring of the rider's performance level
- no possibility to configure and access weather web services
- no management of fins / foils / boards integrated to the quiver
- Full Race / Competition mode:
- 4 jump calculation algorithms
- management / monitoring of the rider's performance level (session + global
- 4 possible choices to configure and access weather web services
- management of fins / foils and boards (kitesurf and similar) integrated to the quiver
For these obvious reasons of different amount of useful memory for the use of an application, it was therefore not possible to integrate all the functionalities of the 1024 KB version into the 124 KB version.
However, apart from the differences mentioned above, everything else is strictly identical and common to the 2 versions (metrics calculated and saved in the FIT file - graph / summary, session and global statistics, etc.).
Clearly, if you want to make a purchase of a Garmin watch, that you do not intend to use the Competition mode and that the estimate of your rider level does not matter to you, a model supporting the 124 KB version only will be enough for you.
Otherwise, or if you already have a 1024 KB compatible watch, you will de facto benefit from all the features.
However, take into consideration, in your choice, the fact that the 124 KB version has reached its maximum potential limit, which means that I will never be able to include new major or important features in the future, unlike the version 1024 KB which is far from having reached its limit!
To summarize, in order to make the most of all the current and future potential of this application, I therefore advise you, in the event of a possible purchase of a Garmin watch and, as far as possible, to acquire a model with at least 124 KB of memory, the best would be a 1024 Kb device, obviously...
Entering the activation code
- for users who have received an activation code, and who can not enter it directly through the integrated menu of the application, it must be entered in the settings of the application using Garmin Connect or Garmin Express applications (DON’T USE THE COPY-PASTE METHOD). Then save the changes, disconnect the watch and launch the application
- otherwise, you can enter the activation code directly from the application's menu: menu -> Options -> Miscellaneous -> Activation Code -> Unlock Code
Preparing and using the app
- launch the app, as any other Garmin app
- then, you have to select the type of practice (kitesurf, windsurf, etc), in the menu options
- you can get the axis of the wind otherwise you will not have access to calculate the efficiency of your trajectory in relation to the wind; this is done by an operation depending your watch model:
• touchscreen models -> general menu then menu "Get Wind Axis"
• models that do not include the management of the advanced control buttons -> long press on the DOWN key
• models with advanced control button management -> long press on the LAP key
- then enter the wind speed (in knots or km/h, option to select in the options menu), if you know it. This will allow you to get charts showing your speed over wind speed ratio, and the one of the wind speed simply; knowing that, if the conditions were to change during the session, it is possible at any time to enter a new value corresponding better to the actual wind speed, or the one you feel. By the way, if you did not enter this wind speed value, the application will work fine, but you will not get these 2 corresponding graphs. Please note that when a wind speed is entered, a small graph on the main screen will appear to simulate this speed, by the color and amplitude of the colored arcs. You can also use a weather web service, which allows you to automatically retrieve those data (see below for explanations on how to proceed).
- then, select a sail / wing in your quiver (the selection is automatic depending on the type of practice selected), or use the calculator that will give you a better idea of the size to choose according to the wind, if you doubt of your choice (see below Quiver Management).
- finally, you can choose and select all other desired options (units, background color, etc.), at any time
- once those "calibrations" have been done, you can start the timer by pressing the START key. However, make sure that the calibration of the initial altitude is done before (small green horizontal bar on the 1st screen) otherwise, the calculation of the height of the jumps will not be accurate (this procedure is automatic and is updated at regular intervals throughout the session to correct any differences due to atmospheric pressure)
- for the practice of kitesurfing (and similar activities involving the management of jumps), also remember to define an algorithm for calculating jumps, as well as the minimum threshold from which jumps will be recorded as new lap in the FIT file (see below the Note on jump calculation algorithms)
- scrolling screens is achieved by simply clicking the UP or DOWN key
- you can pause the session by pressing the START key then "Pause" menu, and resume recording with a second press on the same key then, "Resume" menu (pause = orange dots, active = green dots, stop = red dots)
- on touchscreen models, the pause mode is executed by pressing the START key and then selecting Pause in the menu; to resume the session, you can slide your finger on the screen to the right, or enter the menu again by pressing the START button and select Resume. You have the possibility, in the options menu of the application, to choose to use an automatic pause mode, which will take effect as soon as you take a break (or your speed is less than 1 m/s). This automatic mode also works in automatic restart mode of the session which, when you resume your session and your speed exceeds 1 m/s, will then automatically start, so you do not have to press the BACK button every time you stop or resume your session
- to end the session, you press the START key, a menu appears, proposing you either to reject or save the session. Then, 2 summary screens will be proposed to you, summarizing the main data of the session
- to quit the application in stop mode (when no session has been started), click on the BACK / LAP key, but not on the START one
- the current time is displayed in the following 3 modes: when the session is waiting for launching, in pause mode, and in the minimalist screen otherwise, the timer is displayed.
How to set and use weather web services
First of all, I should point out that this functionality is only available on models with 1024 KB of useful memory for applications, that is to say, applications with mapping and / or music options.
First, go to one of your favorite sites offered by the application:
click on the API tab at the top of the page, then on the orange "Subscribe" button in the "Current Weather Data" area. On the new page, click the "Get API key and Start" button, and follow the instructions. At the end of the registration process, you will receive an email containing your new API key.
click on the "Pricing" tab at the top of the page, a new page opens, click on the green "Sign Up" button in the "Free" area, and follow the steps in the process. At the end of the registration process, you will receive an email containing your new API key
the zone on the left offers you to create a free account (the characteristics of the account are detailed in this zone). Click on the "Start now" button in this area, this opens an account creation form. When you have entered all your information, you will receive a confirmation email and then, when you access your freshly opened account, you will be able to consult your API key generated automatically by the site.
the link directly brings you to the presentation page of the proposed formulas, the free version is on the left, click on the "Sign Up" button, enter the requested information. Once your account is created, you will be able to access the dashboard, which will then give you access to your API key.
Remember to keep this API key, because it can also be used in the future, in case you have to re-enter it in the application following a replacement of your watch, for example.
Your key received, you will then enter it in the application settings, in the field corresponding to the site you have selected. To do this, connect your watch with your smartphone and open Garmin Connect (or a computer with Garmin Express). Select the Wind-Kite Surf application from the list of your applications, and open the settings: four fields appear at the top of the page. Copy and paste your API key in the corresponding field and confirm your entry. There it's done, the API key is automatically transferred to the Wind-Kite Surfing app. Note that yours keys are automatically saved on your watch, in the permanent settings of the application, so you will not have to re-enter them, unless you change your watch.
Note: if the API key has been saved in the field of the settings file, but you can't see the corresponding menu in the web service menu of the application, please proceed as follow:
- activate the bluetooth mode of the watch and connect it with your smartphone then, launch the Garmin Connect application
- launch the Wind-Kite Surfing app on the watch, and stay on the main screen
- on your smartphone, in Garmin Connect, go to the list of the applications installed on the watch, select the Wind-Kite Surfing application and open the settings tab
- the API key(s) should appear; otherwise, re-enter it (them) and save the modifications
- this time, the API keys must have been sent to the application on the watch
Finally, to be able to use this function, and thus recover the wind data automatically in the application:
Result of the request ----->
You have the option to reset two types of data:
Note that the reset is an irreversible function, all data will be lost after this action.
Assign values / scores
This feature allows you to manually assign a value to the data displayed on the "All" screen. This can be useful for example in the case of a replacement / change of your watch, and you do not want to loose all your global statistics. The data entry follows the same order as the data displayed on the "All" screen, to simplify your input.
In order to have the time permanently displayed on screen, you can activate the minimalist screen: this screen presents the essentials and the minimum information, with an extended font (time, chrono, current speed, and the arc of efficiency of the wind + cap followed - as on the screen compass but in a simpler way). It is easily readable during navigation, especially for riders with visual weakness and who can not wear their glasses in navigation.
This screen is activated in the menu of the application - Options -> Display Screens -> Essential Wide -> Activate on/off
When it is activated, it is displayed when the session is started and therefore active. When you put the session in pause mode, the screen disappears to make room for all other screens, so you can, for example, see your performance / detailed information when you pause the session. When you restart your session, the minimalist screen reappears again.
Note: when you have just jumped, the height of the jump is automatically displayed on screen for 10 seconds (the value is then circled by 2 white / black dots to better distinguish the difference from the value of the speed ). This allows you to visualize the height of your jump just after this one, serenely. If, during this period of 10 seconds, another jump is detected and its height is greater than the one displayed, the new height will then be displayed for a new period of 10 seconds otherwise, in case of a lower jump, it is always the value of the previous jump which remains displayed, until the end of the 10 seconds.
Before starting a session, you should first, and preferably, have organized your quiver by adding the sails / wings / fins / foils that you own (for the practice of kitesurfing or similar activities, the management of the fins is replaced by the boards). Then, before starting your session, you select the sail / wing and fin (board) / foil that you are going to use and so, this choice will be saved in the FIT file and displayed in the activity summary as a graph named "Boards/Fins/Foils". Note that you can of course change the sail / wing and fin (board) / foil during the session if the sailing conditions change, which eventually happens relatively regularly, or if you want to compare your performances over several kind of materials.
The management of the quiver integrates a recommended surface calculator: this calculator works in both directions:
1- you enter the wind speed, it offers 3 recommended sizes (a mini, an ideal and a maxi) and, if your quiver is already set, it offers one or two sails framing the ideal recommended size
2- or, you enter a sail size (or select one from your quiver), and the calculator tells you which wind ranges you can navigate with this sail
Management of Run Distances - Speed racing + competition mode
This feature allows you to run on predefined or distances therefore, to perform speed racing or participate in competitions, such as the Wind Challenge for example.
This feature is only available for devices with user memory > 1024 Ko.
This mode offers you the possibility:
- either enter a predefined distance (you can store up to 20), and run on one of these distances
- or run on a distance not determined in advance (free), new distance which will then be stored in the same list (always in the limit of 20)
- start a countdown, going from an immediate duration (duration = 0) to 10 minutes before the start (or the line marking the beginning of the distance to run)
you start the session as usual (START button) then, at the desired moment, you press the LAP button, which will initiate calculations on the distance (chrono + best average speed); if you compete on a free distance, and to end the race, you press the LAP button again, which will stop the timer; if you compete within a predetermined distance, the timer will automatically stop when you have reached the distance (so you do not need to press the LAP key) however, you still have the option to end the chrono manually by pressing the button LAP.
If you have set a countdown, at the start of the countdown by pressing the LAP button, you will see a countdown corresponding to the time you entered in the menu, and whose representation differs depending on the screen on which you you are:
- on the main screen -> the count appears in the 2 blue zones, at the bottom and on both sides of the screen with, the minutes on the left and the seconds on the right
- on the minimalist screen -> the counting appears on the bottom zone, black text on blue sky background;
When the countdown comes to an end, the normal display returns to its place on both screens.
While scrolling the countdown, there may be a lag of one second or more between the full minute of the countdown and the official flag raising. In this case, you now have the possibility to resynchronize the count with this flag raising: you just have to press the START button when the count is close to a full minute, and this one goes automatically set back or up on the full minute.
At any time, you have the possibility to view the history of all the scores made on each of the distances recorded and on which you have competed. To do this, you must go to the corresponding menu (Race - Distances - Settings -> Scores), giving you access to the list, which includes:
- distance indication (in kms / miles or nautical miles)
- the sail / wing and the wing that you used on that distance
- best time and best average speed over the whole distance
Please note that:
- if you run several times on the same distance, only the best lap / fastest lap times are stored in memory.
- for the quiver to be recorded simultaneously with the performance, it is still necessary that you have previously selected the sail / wing surface and the fin used otherwise, none of these 2 data will be recorded. Do not forget to do this before each race otherwise, this data will not appear.
- if you run a greater distance than others in the list, the best chronos + speeds will also be calculated and recorded for these distances, even in free distance mode (if the distance traveled is greater than one of the other lower distances, of course). This is done on the principle of "who can do most can least", based on the observation that if you have run a distance D, you have also traveled all the distances recorded in the list and which are less than D.
- if you select a distance equal to D, and stop the timer manually by pressing the LAP button before reaching this distance, no score calculation will be performed
- once you have started the countdown timer, you can stop it at any time by pressing the START button. To restart it, press the BACK / LAP key again
- once you have started the timer integrating countdown, you have the possibility to resynchronize it by pressing the LAP button again, giving you the opportunity to readjust the situation according to the race conditions
- the corrected altitude value on the main screen will then be replaced by the ratio between your current speed and the max speed reached since the beginning of the chrono / race
Explanations on the submenu of the Race menu
- Set or Select Distance Distance -> allows you to create new distances, select / delete distances, or delete all distances
- Free distance -> activated, you will compete on an indeterminate distance so, free; deactivated, you will compete on a distance that you have previously selected in your list
- Countdown -> allows you to set the duration of the countdown, from 0 mn (immediate) to 10 mn
- Data to Display -> on the Virtual Partner screen, and on the Hall and end of session screens, you have the possibility to display either the chronos or the best speeds (knowing that anyway, the 2 data are automatically saved in the FIT file so that you can be seen afterwards in your session summary on your Garmin Connect profile)
- Alpha500 -> if this option is checked, it is the calculation data of the Alpha500 that will be displayed on the screen of the Virtual Partner, in place of the chrono (or better speed) over a distance
- Scores -> visualization of the results for each of the distances for which a scoring calculation could be carried out
- new option for the minimalist screen: I have also added a new option in the menu of the minimalist screen, allowing you to display the chrono (in large characters) alternately with one of the 3 speeds proposed (so you have now the choice between 3 speeds + 3 additional data)
- additional notes:
1- if you have not created any custom distances, and did not selected the free race mode, the start by pressing the LAP key will not be generated
2- If you have created distances but do not select any for the current session, this will be the first distance from the list that will be used for the automatic calculation of the best speed.
Note about jump calculation algorithms
Depending on the watch models, the application offers 2 or 4 algorithms for calculating kitesurf (and similar practices) jumps:
124 Kb of memory models
Baro + Accel.
algorithm common to all models
equivalent to the algo.2 of the 1024 Kb models
1024 Kb of memory models
Baro + Accel.
algorithm common to all models
algorithm rather suitable for touch screen models
algorithm optimized for button models
maximization of algo.2 → if the results of algo.2 appear to you to be slightly minimized, this algo.3 will aim to maximize them upwards
Anyway, and regardless of the structure of each algorithm, it is up to you to test each of these algorithms to see which one most closely matches your model because, each watch model is different and therefore will not behave like the others, even for 2 identical models which, moreover, makes it even more complicated on Garmin watches when it comes to developing an algorithm supposed to be generic!
The option allowing you to define a minimum threshold corresponds to the minimum altitude from which each jump will be recorded as a new lap (in Garmin Connect) therefore, all jumps below this limit will be well counted and recorded by the application in the FIT file, but will not be materialized as a lap. This option is found in the "Options → Jumps Settings → Jump as Lap" menu.
To avoid the display of a multitude of points as laps on the map of your session, be sure to set this threshold high enough to retain only the most significant jumps of your session, and not all the jumps, otherwise, the map will be oversaturated by points and illegible.
Also keep in mind the consideration of the height of the waves! If you are sailing in a swell of at least 3 meters and your threshold is set to 3 meters, this means that all your detected jumps (even those of 50 cm or less) will be counted as a lap! Which leads to a lot of points on the map (several hundred), even the risk that it will have difficulty to load into Connect.
So, for example: swell of 10 feet + I only want to see jumps >= 16 feet => threshold must be set to 26 feet.
Explanation of the wind efficiency function (principle and operation)
The wind efficiency function shows you the angle between your navigation heading and the wind axis (if it has been set in the application), depending on the sport selected (windsurf, kitesurf, etc.) .
This allows you to better visualize the navigation course to follow in order to optimize / maximize your speed.
The result of this functionality is summarized in the 2 screens presented below, the first displaying in real time the efficiency angle, your bearing and the gauge of your current speed over the wind speed (if it has been filled in in the application), the second, always in real time, the maximum speeds reached in each angle zone over the overall max speed of the session, ranging from -0 ° to -180 ° (right hand) and from 0 ° to 180 ° (left hand), in 20 ° increments.
Note that, on the first screen, the function will also tell you the same information when the session is stopped or in pause mode. In this case, and as you are no longer in navigation therefore, no more navigation course, it is the orientation of the watch on an axis 0 ° -> 360 ° which intervenes, and you will then see the cursor of the course and the angle between this heading over the wind axis moving. This allows you to anticipate, before going on the water, the best trajectories, by looking in advance at the heading(s) which give an angle located in the green zone !
Also please note that this behavior of wind efficiency works the same way into the wide screen "Essential Wide".
In this example, the wind axis is defined to 153°, materialized by the blue cursor, always oriented to the north of the watch regardless of the value of this axis.
Your course is indicated by the black cursor: when you sail west (course of 270°), you form an angle of -117° relative to the wind axis (right hand) therefore, the gauge becomes green and therefore covers an angle of 117°, you are good ! When your heading approaches the axis of the wind, the gauge changes from orange to red (facing the wind) to go back to the left hand (change of tack), until you find a heading which allows you to generate an angle located in the green zone, for example a course of 30° (NE); and so on.
This screen shows you the efficiency score of your speed in each angle zone (ratio between your speed in each zone compared to your average speed per zone combined with the wind speed - if this data exists). The value displayed in the center of the screen is a global combination of all scores by angle area. The median score is at a value of 100, which means optimal overall speed efficiency.
In this example, the most efficient angles (those where your speed is most efficient) are between -80-120 ° right hand and 100-120 ° left hand; the angles between -140 / + - 180 / + 140 ° correspond to the passage of the jibe, which explains a lower speed.
See also the explanatory image below for further details on this screen (seventh screen).
Explanations about the purple gauge, representing your current speed over the wind speed (if it has been defined and saved into the application, either manually or by collecting it via a weather web service).
The gauge works on 2 arcs, one on the top, and one on the bottom:
Hypothesis: if the 2 arcs were filled by the gauge (full gauge of 360°), that would mean that you would be sailing 2 times faster than the wind speed !
Mapping option (compatible models)
For users who own a model with the mapping feature, you have the option of displaying or not the map of your GPS location. This option is found in the menu "Options -> Display Screens -> Mapping". You also have another option allowing you to display or not, superimposed on the map, the representation of your efficiency over the wind axis (efficiency angle between your heading / bearing and the wind axis), according to your practice (windsurfing, kitesurfing, etc.). The color codes are identical to those already used in the other screens of the application (red - orange - green).
note: when you are on the map screen, management is carried out in the same way as in other Garmin applications:
The representation of the wind efficiency offers:
Session and overall Skill Level Screen
This screen shows you your skill level, taking into account a certain number of parameters known by the application, following its use.
It operates cyclically, approximately every 7 seconds, displaying both your performance level for the current session (golden yellow arcs) and your overall performance level (orange arcs). Note that if there is no active session, the screen will only display your overall performance.A first outer circle composed of 6 arcs shows the skills for each of the indicated areas and, once compiled, all these data will generate an overall skill level indicated in the center of the main disk, ranging from zero to 100 (100 meaning the maximum score to be reached ... Antoine Albeau !).
It operates in two stages, real and delayed time, meaning that the skills data integrate the values of the previous sessions but also the data calculated during the current session.
When the application is launched, the skill level is calculated based on certain values known and saved by the application thanks to all your previous sessions. So this is your actual skill level, your current level.
When you start a new session, new data will be calculated and, for some of them, will modify and overwrite the previous ones (especially the data concerning the best scores), which will consequently result in modifying your skill level, possibly upwards.
But if the data of your current session are below your overall skill level (which can sometimes happen - wind less strong, less healthy, misfits, etc.), you'll see the different skill levels, as well as the overall one, to be affected more or less significantly (possibly downwards), then indicating that you have sailed below your usual level.
But, and this is important, it will not significantly affect your previous overall skill level because, you have reached your current level gradually over time, and it can not fail like that because of one or two sessions somewhat below your abilities and usual skill level.
So, to summarize:
- your skill level can only increase over time or, at worst, stagnate or decrease slightly if you cumulate the "trash" sessions, according to the principle: a reached skill level can not be questioned, which is acquired is acquired!
- the data calculated during the current session will only affect your skill level if they are better than the previous ones in a sustainable way; if they are lower, this will only have a temporary visual impact on the different levels visible on the screen, just to indicate to you that this session was at a lower level than your usual level
Note: if you delete the best scores and / or all scores, you will also lose your skill level; you will need to reassign these values to find out your previous skill level
