Your heart rate.
In big numbers.
That's it. Connect your chest strap and do big things.

Chest straps are the gold standard for a reason.
I built BPM because my wrist monitors kept giving me bogus readings, especially during workouts with a lot of arm movement like kettlebell swings and snatches. I wanted readings from a chest strap, on a screen I could actually see. Nothing else.
Chest straps measure your heart’s electrical activity. Wrist monitors use light, which can be thrown off by gripping, wrist flexion, and movement. For lifting and intervals, a good chest strap is the better tool.
Why wrist readings can go wrong“Perfect HRM for me. Its my Fav of the 6 or so I’ve tried. Highly recommended. It pairs quickly every time w my Garmin chest strap. Good selection of screens and layouts. Lets me adjust what I want such as HR ranges for my zones. It gives my HR without averaging it over time so the HR reading is very responsive, which I like when doing HIIT. No need for cloud or login. It just works every time. GREAT APP!!!”

FAQs
Contact usWhich heart rate monitors work?
BPM works with standard Bluetooth Low Energy heart rate monitors. Tested with Polar H10 and Morpheus chest straps.
For HRV, your monitor also needs to transmit RR intervals.
Do I need a separate heart rate monitor?
Yes. BPM displays readings from a compatible Bluetooth monitor. Your iPhone doesn’t measure your pulse on its own.
Is live sharing free?
Yes. Share an invite link or six-digit code. Anyone with it can follow your live heart rate and control your workout or HRV measurement in BPM. Only you can save the results.
Sharing stops after five minutes if nobody connects, or after 90 minutes from the start. Your own workout keeps running.
What does the HRV test measure?
BPM calculates RMSSD from your monitor’s RR intervals over two minutes. Results are calculated on your device and saved to your history.
How are calories calculated?
From your heart rate and profile, with resting heart rate and VO₂ max when available. Active calories exclude resting energy use. These are estimates.
Where does my data go?
Heart rate data stays on your device unless you choose to share or sync it. Optional voice notes use a third-party service with your permission. BPM uses limited usage analytics.
