Features & Capabilities

Cardiograph is a user-friendly heart rate meter app that accurately measures your pulse using your smartphone or tablet's built-in camera or sensor—no external hardware needed. Perfect for exercise, stress monitoring, or managing heart conditions, it records your heart rate instantly and saves each measurement for future reference. The app supports multiple profiles, allowing family members or friends to track their own pulse history separately. Its clean, intuitive design ensures easy navigation, while Wear OS smartwatch support enables pulse measurements directly from your wrist, provided the device has a heart rate sensor. To ensure accurate readings when your device lacks a camera flash, measurements should be taken in well-lit environments. Stay connected and updated through their social channels for the latest features and news.

User Reviews

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.
