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>

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.

App bien plus pratique que les profils proposés d'origine sur ma Venu2s. J ai essayé de mettre de nouveaux profils via les parametres sur Conncet Iq mais la sauvegarde ne fonctionne pas.

Hello Magali and thanks for your comment. It seems that there are currently some issues with settings management by Garmin in Connect IQ since they launch the new System 5 version. Some models are already compatible, others not yet, and for those that are compatible, it seems that group management does not work correctly yet. So, we are still waiting for a fix from Garmin...

Beaucoup de propositions mais pas une seule ne correspond aux premiers rudiments de la cohérence cardiaque. C'est en anglais. Je ne comprends pas les temps proposés.

Resposta do programador
9 de Março de 2022, Surfy66

Bonjour. Qu'entendez-vous par "premiers rudiments de la cohérence cardiaque" ? Le but est simple: respirer le plus calmement et avec le plus de régularité possible, par cycles à choisir selon vos préférences, et l'application déterminera alors automatiquement si vous étiez ou non en cohérence lors de la session, et à quel degré de cohérence. Quant à la langue utilisée, l'anglais, les menus sont relativement simples et aisés à comprendre, d'autant plus qu'il existe une page dédiée à cette application sur mon site personnel, en français, qui explique en détails l'objectif et le fonctionnement de cette application.

O aplicativo parou de funcionar para o relógio Forerunner 235. que pena!

Cool app, COULD be very convenient for HRV training and Biofeedback (not having to stare at a screen for 20 minutes straight and just breathe with your eyes closed feels good sometimes), but it would be important to add the possibility to increase/decrease breath frequency and inhale/exhale duration by 0.1 so that you can actually set your coherence breathing more accurately (mine is 5.5 breaths/min or 4,4 sec inhale / 6.6 sec exhale for example). Not everyone has a "perfect" 5 or 6 breaths/min resonance... If the developer could implement that (IMO this would be more important than the Connect setup if I had to chose) I would give the app 5 stars and recommend it to my fellow breathers!

I think this is a very cool possible app. As others have said it really needs a Connect or Express setup, the on watch setup is very difficult (for me impossible I could not figure out the nested profiles and settings).

Hello Thomas, and thanks for your comment. Okay, okay, I will try to introduce this kind of feature in the next release of the app, promise !

2 de Novembro de 2021 | Versão 2.40

love this app..But please add ability to set it up using connect app..Would make it far easier to use.Due to lack of Connect app settings I gave 4stars..

Best biofeedback application! Thanks.

Great app! Can you write some more info/explanation of different data /results that we get after an exercise?

Just installed the app. It seems to perform well (in comparison to other similar apps which my Fenix 3 crash). To the developer: Thanks for the good work! To other Garmin enthousiasts: Give this app a try.

Merci pour l'app relax cohérence, un peu compliqué de prise en main pour configurer les rythmes de souffle et comprendre la différence entre les 2 possibilités de respiration, une fois compris, c'est parfaitpour apaiser le rythme cardiaque et choisir un rythme respiratoire ou un autre et même utile pour certains Pranayama. j'abuserai si il y avait possibilité de choisir entre fin d'inspir ou d'expir (suspension à plein ou à vide) variable ou fixe.... et des secondes au 10è... pour des pranayama + complexes :) l'App est parfaite pour ma Forerunner 245 music, merci merci

When I go into the app setting on my watch (Venu), the only thing it lets me adjust is whether or not to receive notifications. How do I change it so that I can choose the length and time for the breaths?

Resposta do programador
4 de Setembro de 2021, Surfy66

Hello Amberly and thanks for your comment. When you swipe left on screen (after you launched the app from the watch so, the app is running on watch), you enter the main menu of the app, where you can set and manage all the features and options of the app.

Is it possible to set a breath-hold between inhalation and exhalation? For example, in the Venu 2 watch, there is an exercise Breathing (like 4: 4: 4: 4 mode) with vibration between each phase, but there are no options to change the duration of the phases of inhalation, holding the breath after inhaling, exhaling, and holding the breath after exhaling. Does this feature exist in your application?

Resposta do programador
27 de Agosto de 2021, Surfy66

Hello and thanks for your commet. Yes, with this app, you can set a breath-hold with a duration of your choice between each phase of the cycle. This feature is managed and can be set for each profile you can set up at your convenience.

9 de Agosto de 2021 | Versão 2.39

App qui fait ce que j'aurais voulu trouver en direct dans les exercices de respiration fournis par Garmin : décider du niveau initial, quand on a déjà un peu travaillé sa respiration commencer une séance à 4:4 peut être plus stressant que relaxant. :) Je n'ai par contre pas trouver comment ajouter de nouveaux profils de séance, juste pu modifier les existants.

Resposta do programador
16 de Agosto de 2021, Surfy66

Bonjour Magali et merci pour votre commentaire. L’application peut gérer de 1 à 10 profils max. Pour supprimer un profil existant, vous devez vous rendre dans le menu « Gestion Profils » puis sélectionner et ouvrir le profil à supprimer. Une fois dans le menu des paramètres du profil, allez tout en bas du menu, une option « Supprimer ? » vous est proposée alors. Si le nombre de profils enregistrés est inférieur à 10, vous avez la possibilité d’en créer de nouveaux dans le menu « Gestion Profils » puis « Nb de Respirs » ou « Durée Insp/Expir », toujours en bas du menu.

Very good layout and simple to follow, but why are there 4 values for the coherence?

Resposta do programador
16 de Junho de 2021, Surfy66

Hello Paul and thanks for your comment. The 4 values correspond to the pourcentage of the global time (or session time) you spent from poor coherence to excellent coherence

Merci a toi Belle application utile en ces temps..

Briliant app. Like it a lot. In is in my top 3 for fenix 3 HR. I notice one bug. When FIT activity is set to breathwork on fenix 3 hr app crash. Fortunately it is working really well with yoga settings. THX for a great work.

19 de Abril de 2021, Surfy66

Hello yell and thanks for your comment. The issue is probably because the breath work activity is not compatible with some devices (SDK version related), and this is not documented by Garmin so, I didn't know that. So, thanks for your feedback that helps me to solve the problem. It's now fixed in the new release of the app (version 2.34)

I'm using the app since january. It is wonderful. The last update is awesome! Really suggested. 5 stars really deserved! Maybe, for the future even if for me is not a trouble: italian translation? ;-)

Resposta do programador
30 de Março de 2021, Surfy66

Hello ymarti and thanks for your comment. Italian language is now added to the latest release of the app (since version 2.31). If there are some words / idioms to modify because of a bad translation, do not hesitate to let me know by email, I will fix them with your help. Thanks in advance.

5 de Março de 2021 | Versão 2.20

L'appli est géniale cependant à chaque mise à jour ou autre raison sur la montre, les programmes de respiration personnalisés sont effacés. Il faut tout refaire à chaque fois, dommage, sinon mériterait 5 étoiles Merci quand même

Bonjour Christophe, et merci pour votre commentaire. C'est étrange car j'utilise également l'application, et je ne rencontre aucun problème avec la sauvegarde des profils, que ce soient le nombre de profils sauvegardés, ou leurs caractéristiques propres. De même, tout fonctionne comme attendu dans le simulateur d'applications. Pouvez-vous me contacter par mail afin que nous trouvions ensemble une solution à votre problème ? Je vous en remercie par avance.
