Description by JOhn Lyons Written by the developer, not by AppBrain. Click to read.
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.
