### 1/5 — Bad compatibility

*2025-12-21*

Doesn’t work with ultra watch

### 1/5 — Doesn’t work on iOS 26

*2025-11-23*

Canceling my subscription

### 1/5 — $30 if you don’t want a subscription and only displays health info

*2025-06-10*

$30 if you don’t want a subscription and only displays health info

### 1/5 — Is that it?

*2025-03-20, version 2.8.2*

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

### 5/5 — Top

*2025-01-13, version 2.8.2*

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

### 4/5 — Bonne application mais…

*2025-01-12, version 2.8.2*

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.

### 3/5 — Hmm…slowing down

*2024-12-02*

I started out loving this; I just wanted a complication to track my total calories burned rather than just active calories. Simple enough. This was syncing up beautifully. About a week later…it’s weirdly slightly off by bizarre amounts (100-200 calories) and there doesn’t seem to be a rhyme or reason as to why. It’s not awful, but it does confuse me given its pull data directly from apple health and the Apple Watch - so why isn’t it accurate anymore???

### 1/5 — Great idea, doesn’t seem to work

*2024-07-05*

Great idea, but doesn’t work. Apple Watch Series 9 / iPhone 13 Pro. Was never able to add any of the custom complications to my watch even after reading instructions multiple times. Complications Lab was never available as an option under the watch complications, even after restarting the watch and the phone multiple times.

### 5/5 — Thank you!

*2024-02-28, version 2.8.0*

Was looking for a nice replacement to the Apple activity ring and found your app… just got a lifetime subscription. Great ergonomics - I especially like the corner complication : nice and efficient and I love the fact that it allows me to track activity calories and then with just one tap I can check the distance history for each category of activity : walking, cycling, swimming… and cherry on the cake, Olivier was very reactive to take into account improvements suggestions. Now the app is perfect and works flawlessly! A big thank you for the good work!

### 3/5 — Almost there…

*2024-02-05, version 2.6.0*

Some things here are spot on, such as not collecting any data (no tracking), the simplicity, and pricing. However, I ended up canceling my subscription and will stick to just one complication because there’s no progress happening on key areas: get more health metrics to show, adjust to the new WatchOS, better way to display some complication and widget metrics, etc. Mini-frustrations, but they add up.
