JMG-APP Relax HR Coherence


An application that allows you to relax by lowering your heart rate by defined breathing phases.</p><p>It also makes it possible to check its cardiac coherence, which measures the deviations between each successive frequency.</p><p>The higher the coherence, the more inner calm, the feebler the inner agitation.</p><p>This technique is increasingly used by athletes before a competition or a sporting event in order to be better prepared for it.</p>

Well thought out, very poorly implemented. Constantly crashing and during the exercise. This is how this app is unuseable

J'ai une Forerunner 735 XT et l'appli n'a pas l'air de fonctionner, est-ce normal ?

Bonjour Bertrand. Lorsque je fais tourner l'application dans le simulateur avec votre modèle, tout fonctionne parfaitement. Donc, pouvez-vous me contacter par mail afin que nous puissions déterminer avec plus de détails ce qui ne fonctionne pas sur votre montre, et tenter d'en déterminer la cause ? Peut-être cela provient-il de votre montre, et non de l'application ? Avez-vous procédé à un soft reset de votre montre, cela résout souvent ce genre de problème. Merci à vous.

The app is great, but there is one thing: the hold/breathe notifications does not come when the screen is off on OLED devices, specifically EPIX 2. When I tap on LIGHT button to turn the screen off (because I don’t look at at and just do the breathing) to preserve battery, the whole app seems to freeze - the notifications are not coming and the timer seems to stop. Once I turn screen back on - everything resumes, but it’s a pity that the screen need to constantly be on. This is surely not a problem on reflective screens, but since GARMIN is slowly moving all their devices toward OLED, I think the developer should consider this as a major bug. I’m happy to assist you with debugging if I can.

Hello, Can't turn on shows IQ

Hello, The app randomly freezes in the middle of each activity. It continues to record data, but the screen / vibrations stop every time after a minute or two. This happens regardless of whether I touch the watch during the activity. Any know way to fix this? Vivoactive 4 Thanks

Great app! Just a clarification: on the drawing rectangle is ‘hold for 2 sec’ but on the explanation under is ‘hold for 12 sec’!

Merci pour votre retour Arnaud. Cette fonctionnalité ne pose pas de problème lorsque je fais tourner l'application dans le simulateur pour votre modèle. Avez-vous vérifié que l'option est bien activée dans le menu Options de l'application, et que les vibrations sont également bien activées dans les paramètres globaux de votre montre ? Sinon, vous pouvez prendre contact directement par mail afin que nous tentions de trouver ensemble d'où cela peut provenir.

Hello Pawel. There are absolutely no errors identified by the error reporting tool (ERA) concerning this application, the list is empty. If the application contained a bug generating a crash on your watch model, the source of the problem should appear in the list, allowing the developer to correct the bug in question, which is not the case here so, what can I do ? Can you contact us by email, so that we can investigate your problem in more detail?

Hello Lason and thanks for your comment. Yes it's possible, of course. Can you please reach me by email and I will explain to you how to do it. This is not the place to do it here, not much room for it.

25. december 2022 | Različica 2.58

Great app, a lot to manually set up according to my preferences and easy to use. I think it's the best breathing app for garmin so far.

Hello Jan and thanks for your comment. Always on lighting is not possible, even by coding, the backlight runs only for a limited time, and this is set in the general settings of the watch.

Great app but latest version has issues and crashes often. Results are not recorded properly. Is it possible to fix issues or allow to downgrade to previous one?

08. november 2022 | Različica 2.56

Hello App was great but since few weeks does not work anymore, the screen is just frozen, nothing is recorded. (935) ☹️ I hope it can/will be fixed. Thank you

Hello Tyler and thanks for your review. Garmin recently changed the format of the settings file and some of the devices are still not compatible with this new management. However, the app offers a full integrated menu where you can set up the app with ease, without having to use Connect or Express (when the app is launched, just long press the UP key, or swipe-left on screen on touchscreen devices).

confused, installed and it will out of sudden become not installed on app, also quite confused what this app can do?

Odgovor razvijalca
14. avgust 2022, Surfy66

Hello Eric. Another bad rating even though the application is not the cause of this malfunction... Do you really think I would come up with an app that would never appear on watches like, a ghost app? So, the issue is to be found elsewhere, and is most likely caused by Garmin Connect not being able to install the app on your watch because Connect cannot read your firmware version. Therefore, you must perform a soft reset of your watch then reinstall the application, it should then appear in the list. A soft reset is to be done in all cases after installing a firmware update, this avoids this kind of malfunction.

I cant connect via bluetooth, getting error so cannot change any settings. Any ideas please?

Odgovor razvijalca
02. avgust 2022, Surfy66

Hello Fritz. The bluetooth connection between your watch and your phone is not managed by the app itself but by the watch. So, verify your connection and sync parameters. You can also use Garmin Express if you experience some issues with your syncing process or, even better, the app offers a full integrated menu where you can set up the app with ease, without having to use Connect or Express (when the app is launched, just long press the UP key, or swipe-left on screen on touchscreen devices).

Bonjour App works well and thanks for developing it. I found 2 issues: - when starting the activity the LiveTrack is starting. It is configure to start automatically for activities using the GPS, I'm not sure why we need the GPS in this case. - when exercise is done, the activity do not stop itself like other activities, I forgot to stop it last night and in the morning the battery was totally empty because of this. I hope you can improve these. Good day :)

07. maj 2022 | Različica 2.52

Bonjour, this app is exactly what is expected for managing breathing exercices. 2 remarks anyway one not important : the sound & vibration is stopped when you swap to 3rd screen during exercise why ? The second is more foundamental : I like to have my coherence status in live i.e in the main screen, I thougth it was the coulour in the bottom right zone, but it seems that it is more a HR comparator to the starting HR. That is questionning me on how you calculate Heart coherence. can you confirm ? And thank you very much Jean-Michel for this work and sharing

Bonjour Olivier. To answer your questions: 1- I think that the third screen you are talking about is the stats screen. In the options menu, you have an option where the user can enable/disable notification alerts, either on gauges screens only, or on all screens. So, I guess your option may be set to disabled. 2- you are right, on this screen, the color, on the right area of the screen, changes according to the HR value compared to the starting HR. In the latest release of the app (version 2.53), you have now the display of the color changing accordingly to the stress zone, on the left area of the screen.
