Heart Sit — Meditation Heart Rate via AirPods Pro & Apple Watch

Requirements

Heart Sit requires:

Without either AirPods or Watch, the app still works as a meditation timer with overtime mode and session journaling — but no live heart rate.

Getting Started

  1. Open Heart Sit and grant HealthKit permissions when prompted
  2. (Optional) Type a short intention on the home screen
  3. Pick a session duration — quick presets at 5 / 10 / 15 / 20 / 30 / 45 / 60 minutes
  4. Tap Begin — the app starts a 5-second warm-up countdown
  5. Lock your screen and close your eyes — Heart Sit keeps running with a near-silent audio loop so the bells fire on time
  6. When the bell rings, your session is complete — tap STOP if you're in overtime mode
  7. Review your session detail with the OBSERVED insight banner, settle score, HRV, and BPM chart

Frequently Asked Questions

Why can't I see my heart rate?

Make sure either AirPods Pro (worn in your ears) or Apple Watch (worn on your wrist) is connected and that you've granted Heart Sit access to HealthKit (Settings > Health > Data Access > Heart Sit). Heart rate data typically appears within 5–10 seconds of starting a session.

Does Heart Sit work with Apple Watch?

Yes. Heart Sit reads heart rate from any HR-capable Apple Watch model. When you open the Heart Sit Watch app during a meditation, it forwards your live BPM to the iPhone in real time. The Watch app also functions as a remote — you can pause / resume / stop from your wrist.

Can I lock my phone during a session?

Yes. Heart Sit supports background execution. Lock your screen, put the phone down — the session continues with heart rate capture, timer, and bells all running in the background.

Where is my data stored?

All session data is stored locally on your device. Nothing is sent to any server. See our Privacy Policy for full details.

How do I export my data?

Open any session in Session History, tap Export CSV at the bottom. The file will be shared via the iOS share sheet — pick your destination (Mail, Files, Notes, etc.).

How do I delete a session?

In Session History, swipe left on any session to reveal the delete button.

Can I customize the interval bells?

Yes. Open Settings, enable "Interval Ding," and use the slider to set intervals from 30 seconds to 10 minutes. You can preview the sound before applying.

Does Heart Sit use any internet?

No. Heart Sit makes zero network requests. The app works entirely offline.
