Beat Watcher helps you stay aware of your heart rate on Apple Watch with customizable high and low BPM threshold alerts. Beat Watcher integrates with the Health app to read your heart rate. Use Beat Watcher for: - listening to your body during daily routines - stress awareness and breathing exercises - meditation and mindfulness - workouts and pacing - sleep or rest check-ins - staying aware of high or low heart rate readings Some users with POTS or ME/CFS use Beat Watcher as part of their own pacing and body-awareness routines. Beat Watcher is not a medical device and does not diagnose, treat, prevent, or manage any condition. Turn the Digital Crown on Apple Watch to set the desired BPM threshold. Then, you will 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. Enable Low Alerts in Settings to also get notified when your heart rate drops below a second threshold you set. Stay aware of high and low heart rate readings at the same time. Install the free Beat Watcher companion app on your iPhone to receive phone alerts when your heart rate crosses a threshold. Turn on Critical Alerts to hear a loud sound even when your phone is on silent or Do Not Disturb, so you or someone nearby can notice the alert during sleep. The iPhone companion also keeps a local Alert History so you can review saved alerts, add a note and preset context tags, and export saved history as a CSV file. 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 or below your set thresholds. Or, if you just want a continuous heart rate display 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 are not wearing it, like when it is 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.
