Overview
- Ultrahuman began rolling out the new Heart Scan on Oct. 7, 2026, letting eligible Ring Air and Ring Pro users run on-demand rhythm checks from the app.
- Each Heart Scan lasts 60 seconds and uses the Ultrahuman Ring's sensor with FibriCheck's clinical algorithm to classify rhythms in real time.
- Scan results appear inside the Ultrahuman app and generate a downloadable FibriCheck PDF that includes the pulse recording, a tachogram, and a Lorenz plot for clinician review.
- Availability depends on region and app version—Ultrahuman requires iOS app 4.3.0 or Android 3.2.0.0 for supported markets, and eligible members can enable free scans from the Ultrahuman dashboard.
- Ultrahuman and FibriCheck warn the feature has limits: results can be 'Regular,' 'Possibly irregular,' 'Possible atrial fibrillation,' 'Signal quality too low,' or 'Inconclusive,' the scan does not detect heart attacks, and nightly AFib screening remains a paid PowerPlug subscription.
