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. ### 3/5 — Has potential *2026-01-29, version 2.1.3* 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. ### 3/5 — Ok *2025-08-22, version 1.8* Not a fan of the sign up process that says “free free” and then would charge you 5€ per month to continue with the setup. Aesthetically the app is very pleasing. ### 4/5 — Almost excellent *2025-08-21* Love the layout. Sleep data broken still, otherwise I pre-ordered this app months ago and i’m so happy it’s here ## Most praised reviews (9 highest-rated) ### 5/5 — Excellent *2026-03-13* Well, done review. ### 5/5 — great app *2025-08-28* big fan of the hydration feature ### 5/5 — Better than whoop *2025-08-28, version 1.9.2* And you don’t need to buy new hardware! ### 5/5 — Love this app *2025-08-28, version 1.9.2* I am an Oura ring user and have used several fitness tracking apps before, but Perform is one of my favorites. I love that it gives me a battery gauge throughout the day and tells me when I need a recharge. ### 5/5 — Best app ever *2025-08-15* Love this app so much! ### 5/5 — Awesome App *2025-08-14* Perform makes it easy to track and understand data. The AI feature is also a game changer. ### 5/5 — great for v1 *2025-08-14* excited to see how this app evolves! ### 5/5 — WHOOP Killer *2025-08-13* Awesome interface and insights, have been waiting for this to release and so far impressed with all the data and insights. ### 5/5 — Nice looking app *2025-08-12, version 1.03* Cool stuff --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
