Track your heart in real time, right from your wrist. This app requires an Apple Watch, and includes the watch app free.
This app shows live heart rate with a smooth scrolling graph, along with key cardio signals like energy burn, breathing rate, and variability, designed for clarity at a glance.
Built for Apple Watch first, it focuses on continuous monitoring, not workouts. No clutter, no sessions to manage — just instant feedback on how your body is responding moment to moment. An optional iPhone companion mirrors your data on a larger screen.
Perfect for casual fitness, stress awareness, or simple curiosity about your heart throughout the day.
The app comes with a companion watch app you need to run at the same time.

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
Write to [email protected], or use the form. Name the finding, the app version and the evidence that needs correcting. Factual corrections are free and never depend on buying anything.
