• A major new feature has been added for this weekend, August 15 😃: the Cloud Access Pack (all HIGH 1024 versions are eligible, plus the HIGH 124 for the Downhills and Pumptrack apps).
This feature allows you to back up and restore your app data from a secure cloud storage space, to prevent any loss in the event of a watch change, reset, or service intervention.
Data common to all apps involved in synchronization:
- app activation credentials (ID + code)
- overall statistics, last session, and session history
and additional data for the following apps:
- All routes created with their full details (location, distance, etc.) → Downhills
- API keys for weather services → Foiling, Surfing, Wakeboarding, WindKite Lite, and Pro
- Complete quiver → WindKite Pro
- distance/route table (Race Distances) → WindKite Pro
- phone book (emergency numbers) → WindKite Pro
- automatic update of the world speed records table → WindKite Pro. If the Cloud Access option is enabled, the “World Speed Records → Update Records” menu will appear under the “Display Records” menu
Key benefits:
- quick data restoration after replacing or resetting the watch
- automatic reactivation of the app ("Activation Code → Restore ID + Code" menu)
- multi-app synchronization via a single Cloud ID
- manual backup at any time ("Cloud Access → Upload / Download Data" menu)
Activation:
purchase from the online store at “https://www.jeanmichelgruber.com/store-eng.html” then enter the code received via email in the “Tools → Cloud Access → Activation” menu.
Compatibility:
The “Tools → Cloud Access” submenu must be visible in the app.
If it does not appear, this means that the model or version is not eligible.
The introduction of cloud access also lays the groundwork for future developments: viewing statistics online, session sharing, and other services still under consideration—all focused on ease of use.
Detailed documentation is available in the user manual for each applicable application.
Video tutorials are available on the YouTube channel or on this website (video tutorials)
• in fact, the manual score assignment feature (formerly the “Scores → Assign Scores” submenu) has been removed for all these versions across all affected applications. This process, which was somewhat tedious, is no longer necessary with the introduction of the Cloud option. Furthermore, this has freed up a significant amount of memory, particularly in the HIGH 124 versions, which has made it possible to include the Cloud option for this version in both the Downhills and Pumptrack apps.
• for all versions eligible for this Cloud feature: a pop-up message has been added that appears when the app launches to inform the user of important new features in the latest update.
This message appears only once, upon the first launch following the update.
For future versions, the display can be selectively reactivated, only when essential information needs to be communicated.
Goal: to clearly highlight major additions (such as Cloud access) without interrupting the user every time the app is opened.
• simplification of the “Tools → Activation Code” menu
• update of all user manuals
JMG-WGT WindKite Lite (version 1.42)
JMG-WGT WindKite Pro (version 4.76 and 4.77)
• HIGH 124 and HIGH 1024 versions: A new hybrid jump calculation algorithm (in beta version) has been added, replacing the previous “Baro + Accel” algorithm, which is likely rarely used by the community today. This new algorithm combines barometer data, free-fall detection, and kinematic validation. It is more accurate, more stable, and should provide more consistent results, particularly for medium and long jumps. For the HIGH 124 version, this new algorithm appears at the top of the list in the menu for selecting different calculation methods, and for the HIGH 1024 version, it is displayed in the automatic configuration window in purple (to distinguish it from other existing non-beta algorithms)
— I welcome and need your feedback 😃 (via email or on this website (https://www.jeanmichelgruber.com/contact-eng.html page)
This new hybrid algorithm needs to be put to the test in real kitesurfing conditions (since I only windsurf on flat water, I can’t test it in real-world conditions)
So please don’t hesitate to share your results, comparisons, and observations with me after your sessions.
Your feedback will help me determine whether I can keep this algorithm as is (and release it as the final version), make a few adjustments, or—on the contrary—remove it because it’s unreliable or ineffective.
Thank you very much for your participation and your help!

• HIGH 124 and HIGH 1024 versions: complete rewrite of the jump management code. In principle, the responsiveness, speed, and reliability of jumps should be even better than before
• HIGH 1024 version only: added a new metric—the calculation of top speed over a nautical mile (1,852 meters). In the WindKite Pro app, this new metric now appears on all screens where the Alpha500 calculation is displayed (alternating with it), except on 2–3 statistics and/or end-of-session screens, where only the Alpha 500 speed is calculated and displayed. In the WindKite Lite app, it is displayed on the second screen, alternating with the Alpha500 calculation. And for both apps, this new metric is also available as a new display data point for the Wide Screen, and is recorded and saved in the FIT file on the same line as the Alpha 500
• a few minor adjustments and fixes to the alignment of certain text (snapshot screens) and optimization of certain portions of the code
• update to the user manual
JMG-WGT WindKite Pro only, HIGH 1024 and HIGH 124 versions (mise à jour 4.77):
• improvements to the management of world speed records. In this new version, the various world speed records are no longer assigned solely based on the selected discipline, but also according to the rider’s gender (female or male)—which makes it more consistent!
• HIGH 1024 version only: creation of a new snapshot-style screen, accessible via the “Tools -> World Speed Records” menu, which allows you to view all world records for every discipline available in the app, with the women’s category on the left side of the screen (in pink) and the men’s category on the right side of the screen (in blue). For more details, please refer to the user manual, section “Displaying the World Speed Records Table”, available here
JMG-APP Relax & HR Coherence (version 3.18)
• reintroduction of compatibility for the Fenix 3 / HR and Forerunner 230 / 235 models
JMG-APP Surfing (version 2.94)
• on the statistics screens (screenshots), we fixed a bug that was counting the total number of rides during a session twice. As a result, the total number of rides was twice what it should have been. This bug has now been fixed.
JMG-APP WindKite Pro (version 4.75)
JMG-APP WindKite Lite (version 1.41)
• the app’s main menu has been partially restructured (added a new “Activity” menu, which now groups all activity-related features and options; a new “Safety” menu that brings together all safety-related features in one place; a new “Display Settings” menu, etc.); As a result, the “Options” and “Tools” menus have been streamlined; over time, with the successive addition of new features, they had become somewhat cluttered and hard to navigate. The main menu should now be more readable, more consistent, and easier and faster to use 😉
• under-the-hood improvements and code optimizations
JMG-APP WindKite Pro (version 4.72)
JMG-APP WindKite Lite (version 1.40)
• in the HIGH 1024 versions of the app, the menus for managing jump settings and the quiver have been simplified to reduce the space taken up by the numerous menus. Since these menus are accessible via the quick-select windows, they have been removed for the sake of simplicity
• optimized the display of the quiver selection window
• updated the user manual
• compatible with the new D2 Mach 2, D2 Mach 2 Pro, Forerunner 70, 170, and 170 Music models

JMG-APP Surfing (version 2.93)
• compatible with the new D2 Mach 2, D2 Mach 2, Forerunner 70, 170, and 170 Music models
JMG-APP WindKite Pro (version 4.71)
- fixed a minor bug on models with a 260x260-pixel screen resolution related to the Virtual Partner, which caused the app to crash when the user tried to display the VP screen. The issue has now been resolved
- app compatible with the new D2 Mach models
JMG-APP Relax HR & Coherence (version 3.11)
- models with at least 1024 KB of usable memory:
• on the history screen (fourth screen), the number of sessions that can be displayed increases from 15 to 21 plus, unlocking the second sub-screen (stress history + average RSA) only if you purchase the in-app option for 7USD; otherwise, this number remains fixed at 15 sessions, just like before. Your contribution to the purchase of this option allows me to continue working on the application, improving it by adding new features (as in this new update), and maintaining it to offer you an application that is increasingly powerful and enjoyable to use on a daily basis.
• on the HR graph, added the average HR per exercise, symbolized by a small horizontal line in white (on a black background) or black. (on a white background).
• on the second sub-screen of this fourth screen, added the average RSA graph for each session + line representing the average for all sessions displayed (purple line).
—Note: apart from this small change in the display of the number of sessions, all other features of the app remain unchanged, so it is still completely free with no limitations 😉
- models with less than 1024 KB of usable memory:
• on the history screen (fourth screen), the number of sessions that can be displayed is reduced from 15 to 10 in order to reduce the memory space occupied by the data table, thus leaving more space for the application to function properly and to be consistent with the limited number of the version running on 1024 KB models.
- for all models:
• combining the old screens 2 and 3 into a single screen, which becomes a single second screen, divided into two sub-screens: large-format gauge display during exercise, then switching to graph display at the end of the session (memory gain and code reduction)
• the breathing gauge now has 4 colors (instead of 3 previously), making the color gradient effect smoother
• complete redesign of the main screen with the addition of explicit images and icons (more modern and attractive than before 😏)
• modification of the HOLD phase display (new, more visible gauge with countdown display)
• touchscreen models: on the main screen, replace the long press with a single tap on the two images at the bottom of the screen to change the auto-save status and the type of FIT file (breathing exercise or yoga)
• overall and in-depth optimization of the code (increased fluidity, less memory usage, etc.)
JMG-APP Apnea Training (version 2.10)
• Christmas is coming...🎄 and so here is a major update, with the addition of a brand new statistics dashboard, including 3 complete screens, presenting targeted data relating to your progress over successive sessions. I invite you to read the user manual on this page to learn more about these new screens (as well as the descriptive images at the bottom of the page).
This statistical dashboard is displayed via the “Tools -> Stats” menu, but requires an activation code to be unlocked, which you can do by clicking on the “Unlock Stats” button at the top right of the Apnea application page.
• compatible with the new D2 Mach 2
