Review summary

The app struggles most with reliability and compatibility. Many reviews report it won’t start, stops working after updates, or behaves inconsistently across devices and Android versions, with camera/flash usage sometimes causing issues. Readings are often described as inaccurate or stuck at 0 bpm. A minority praise the clean UI, continuous readings, and potential medical usefulness when it functions. Overall, reliability and hardware/OS compatibility are the dominant pain points, with occasional positive experiences when the app operates correctly.

Pros

Clean, simple UI.
Continuous heart-rate reading feature.
Some users report accurate readings when it works, including matching a pulse oximeter.
Perceived medical usefulness and potential life-saving value when functioning.

Cons

Frequent reliability issues: app often fails to start or stops measuring after launch or during use.
Significant device/OS compatibility problems across models (e.g., Pixel 4a/8/10, S24 Ultra) and Android versions (Android 15), plus camera-based measurement limitations.
Updates/regressions that break functionality or reduce accuracy after newer releases.
Inaccurate readings and intermittent zeros (0 bpm) when measuring.
Flashlight/camera-related issues: high flash intensity causing overheating or unsafe usage in some cases.
