Beatcast: Heart Rate Monitor for iPhone

Beatcast is a heart rate monitor for iPhone and iPad. Pair a Bluetooth sensor and the number stays on screen in other apps.

Start a session and your heart rate moves into the Dynamic Island and onto the Lock Screen. Glance, do not unlock. The videos here show the rest: pairing a sensor, setting zones for a strength session or for winding down, and what you see between sets.

Most straps and bands connect, worn wherever you prefer. Free to try for 14 days, then a one-time purchase. No subscription.

Some scenes in these videos are made with AI. The app screens are real recordings of Beatcast, mostly from a simulator with simulated heart rate data. Jumping around to get a heart rate up for every take got tiring.
