Beat Watcher: Stress Monitor

This simple app is designed to do one thing well: alert you when your heart rate goes above and back below a BPM threshold you set.

Beat Watcher integrates with the Health app to read your heart rate.

Use this app as a way to listen to your body.

It can be great for:
• recognizing and managing stress
• breathing exercises
• meditation
• working out

Some users with Postural Orthostatic Tachycardia Syndrome (POTS) and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) have found this app helpful for monitoring and managing symptoms.

Turn the Digital Crown on Apple Watch to set the desired BPM threshold. Then, youll hear a sound and feel a vibration when your heart rate goes above the threshold, and a different sound and vibration when your heart rate goes back below the level you set.

Optionally turn on Background Mode to continue getting haptic and audible feedback in response to your heart rate after you drop your wrist or leave the app.

Enable the Persistent Alerts setting to continue getting haptic and audible feedback every two seconds while your heart rate remains above the set threshold. Or, if you just want constant heart rate monitoring without the haptic and audible feedback, you can turn Alerts off entirely.

This app also works with a Bluetooth chest strap heart rate monitor, like the Polar H10, paired with your Apple Watch. Using it this way can improve battery life of the Apple Watch when you leave Background Mode running for a long time, since your Apple Watch heart rate sensor is not running constantly. Also, this lets you continue getting audio feedback from your Apple Watch or see your heart rate on the Apple Watch screen even when you arent wearing it, like when its on the charger.

Note: Background Mode will not work at the same time as a Workout started in another app. For example, if you start Background Mode in Beat Watcher and then start an Outdoor Run Workout in the built-in Workouts app, Beat Watcher will not continue to run in the background.

This app requires watchOS 8 or newer, which requires Apple Watch Series 3 or newer.
