A premium monthly price without any of the features necessary in 2026

Excellent

Well, done review.

Has potential

Its not a great replacement for my whoop but maybe after my subscription is over ill get an alternative band and will come back to this one.

Missed potential

The app promised so much but delivered so little.
The concept is great and I really like the hydration streak an challenge.
Negative points are:
- App crashes every second time when I open it (17 Pro Max with iOS 26.0.1
- UI bugs all over: No liquid glass, bar charts look bad when the data is higher than the target or when the value isn't divisible by ten, automatic theme switching between light and dark mode based on the system does not work an stays always in light mode
- No charts for the development of strain, recovery and sleep score available.

It's more of an app to tell you what's going on with your health data on the present day rather than telling you your developed your health.

All in all: The current version is a waste of money for the Peak+ subscription. It offers hardly any value, the app is unstable and not maintained. The iOS 26 Health App is the better option for most users.

I hope this app will be optimized. I won't be renewing my subscription for it when the subscription period is over. Feels like money wasted on a good idea with suboptimal delivery.
