Is that it?

Why so few metrics? Where is just calories or resting calories burned?

Setup was easy and everything just works. The app looks great and works well, unlike WatchSmith.

Bonne application mais…

L’application offre une large personnalisation de votre  Watch, cependant :
- les complications ne se mettent à jour que toutes les 15 minutes ce qui est assez embêtant car les informations données sur votre cadran ne sont pas forcément à jour. Il faut à chaque fois ouvrir l’application en touchant une complication pour que ça se mette à jour ;
- certains bugs persistent comme la non synchronisation des informations entre l’application Santé et celle-ci. La durée du sommeil par exemple n’est pas du tout synchronisée avec l’application alors que toutes les autorisations ont été cochées.
Merci de corriger ces éléments.
