A few
good questions.

Something else on your mind?

Which heart rate monitors work?

Bluetooth Low Energy monitors that use the standard Heart Rate Profile should work. BPM has been tested with Polar H10 and Morpheus straps.

For HRV, your monitor also needs to transmit RR intervals.

Why does this app exist?

I wanted a chest-strap app that just shows BPM in big numbers. So I made one out of spite and laziness.

Do I need a separate heart rate monitor?

Yes. BPM displays data from a compatible Bluetooth monitor, such as a chest strap. Your iPhone doesn’t measure your pulse on its own.

Is live sharing free?

Yes. Share your session code with someone so they can follow your live BPM. Sessions automatically expire after 90 minutes.

What does the HRV test measure?

BPM calculates RMSSD from the RR intervals sent by a compatible monitor. Keep the app open for the full two-minute test. Results are calculated on your device and saved so you can follow your trends.

How are calories calculated?

BPM estimates calories from your heart rate and profile, using resting heart rate and VO₂ max when available. Total calories include resting energy use; active calories subtract that baseline. Treat these as estimates for tracking trends.

Where does my data go?

Your heart rate data stays on your device unless you choose to share it. You can also save workouts to Apple Health and sync history through iCloud. BPM uses limited, non-personal usage analytics to improve the app.
