Holter mode

A whole night on one strap, one PDF for your doctor.

Holter mode records from a Polar H10 for a whole night or up to 24 hours and turns it into a PDF report you can bring to your doctor: heart rate and variability over time, the fastest and slowest moments, the longest pauses, and every flagged possible pattern with its ECG strip.

  • Overnight or 24 hOne long single-lead recording with a Polar H10; the app keeps the Bluetooth stream going while the phone is locked.
  • One PDFSummary, heart rate and variability charts, 25 mm/s strips, an event table and the methodology, in English or Polish.
  • On your phoneThe analysis runs on your iPhone. The report leaves the phone only when you share it.

RytmoECG is a wellness app, not a medical device and not a certified Holter monitor. The report shows possible patterns to look at with a clinician, not a medical verdict.
