ECG Recorder for Chest Straps
Live ECG, doctor report & PDF · for iPhone · Status: preparing for the App Store
Works with the Polar H10. Other chest straps show heart rate only.
Record your ECG from a chest strap – live, in the background and for hours. Mark moments, scroll through the recording and create a clear PDF report for your doctor.
Record
- Live ECG like a bedside monitor, plus heart rate, battery and skin contact
- Keeps recording when you lock your iPhone or leave the app
- Optionally starts recording by itself once the strap connects – and warns you when its battery runs low
- Reconnects automatically after a dropout; gaps stay visible
- Mark what you felt or did with a single tap
- Movement trace from the strap's accelerometer – see whether a restless stretch comes from moving
Review
- Scroll like a paper roll, pinch to zoom
- Classic ECG grid, gain 5 / 10 / 20 mm/mV
- Heart rate and movement over the whole recording – tap to jump there
- Beat-to-beat intervals with SDNN, RMSSD and a scatter plot – the numbers, without interpretation
Share
- Doctor report: overview with key data, heart rate trend and your markers, plus 30 seconds of ECG for each marker
- Any section as a PDF at 25 mm/s – share it or print it straight to an AirPrint printer
- Raw data as CSV, heart rate and beat-to-beat intervals (RR) each as CSV, or everything as EDF (standard format for ECG software)
- Every export lands in the app's own folder in the Files app – also reachable by cable or Finder
- Optionally writes the heart rate of a recording to Apple Health
Your data stays with you
No account, no server, no ads. Recordings stay on your iPhone and only leave it when you export something yourself. More in the privacy policy.
Not a medical device
The app records and displays the signal but does not analyse it or provide a diagnosis. It does not replace a medical examination. If you have symptoms, see a doctor; in an emergency, call your local emergency number.
