70 BPM for iPhone — Your Heart Rate, Lined Up With Your Day
The iOS app reads heart-rate samples already in Apple Health and lays them over the meetings and events on your calendar, all on the phone.

What 70 BPM does on iPhone
The iOS version specifically — what it is built around and what it does differently from the other versions.
70 BPM is an iPhone app, and it is built around two things that already live on the iPhone: the heart-rate samples in Apple Health and the events in your Calendar. It reads both and draws one chart — BPM across the day, with your meetings, focus blocks and events marked on the same timeline.
It does not measure heart rate itself. The samples come from an Apple Watch or another device that writes to Apple Health — Garmin, Oura, Fitbit, Polar and others via their own apps. Full-day sources such as Apple Watch, Garmin and Oura fill the chart best; a chest strap that only records workouts will show gaps.
Everything is processed on the iPhone. There is no account, no web dashboard and no upload — the chart is drawn on the device that already holds the data. 70 BPM is not a medical device.
On iPhone you get
- Calendar-aware heart rate. BPM matched against what was actually on your schedule.
- A day chart built for scanning. Zones, dense or sparse detail, bars or line.
- Event focus. Open a meeting or block and see the samples that fell inside it.
- Focused Tracking. Denser sampling during important timed events using an iPhone workout session — data still arrives through Apple Health.
- Home Screen and Lock Screen widgets. Today’s average heart rate at a glance.
- Siri and VoiceOver. Siri can access the app; the interface supports VoiceOver.
- Six languages. English, Spanish, French, German, Hindi and Japanese.

FAQ
Questions people ask before installing on iOS.
Does 70 BPM need an Apple Watch?
It needs heart-rate samples in Apple Health. An Apple Watch is the most common source, but Garmin, Oura, Fitbit, Polar, Whoop and others can write to Health through their own apps.
Is there an Apple Watch app?
No. 70 BPM is an iPhone app. The Apple Watch is a data source — it writes samples to Apple Health, and 70 BPM reads them on the iPhone.
Does it upload my health data?
No. Processing stays on the iPhone. There is no account, no web view and no server. Put the phone in airplane mode and the app works the same.
Which iOS version do I need?
iOS 18.0 or later.
