Initially designed as app available on prescription from a doctor.  Some doctors still "prescribe" the app in this way or it is now available for public purchase through the App store or Google play store (12 months subscription is €10 per month). Once the app has been downloaded onto a smartphone the heart rate and rhythm can be detected through the smartphone's camera by placing a finger on the camera for 60 seconds.

A portable handheld device which can detect the heart rhythm and heart rate when two fingers are placed on the sensors.  The measurements are transferred by the mobile network to a central database, where they are presented to your designated care provider/ doctor for further analysis.

The series 4 Apple watch has electrodes built into the digital crown to work with the ECG app so when a finger is placed on this area it is able to read your heart’s electrical signals.  After 30 seconds, the heart rhythm is classified as either AF, sinus rhythm or inconclusive. All recordings, their associated classifications and any noted symptoms are stored securely in the Health app on iPhone. Users can share a PDF of the results with physicians.

This app can be downloaded for free but the user needs to purchase a monitoring pad (Kardiamobile) or a special strap for an Apple watch (Kardiaband) to monitor your pulse with the app. Users place their fingers on the monitoring pads which detect the heart rate and rhythm, providing a reading after 30 seconds, indicating a normal rhythm or AF.
