ECG Catch records ECG from a Polar H10 chest strap. The app always keeps the last 2 minutes. When you press the red button, they are saved together with the next 2 minutes – 4 minutes of ECG in total. HOW IT WORKS • Moisten the electrodes and put on the strap. The app connects by itself. • Use your phone as usual. The app receives ECG even when the screen is locked. • Press when you want to keep the ECG: in the app, on the Lock Screen, in Control Center, with the Action button or with Siri. • Add a note about what you were doing. SHARE AS PDF The recording is shared as a PDF on standard ECG paper (25 mm/s, 10 mm/mV), marked with when you pressed and the heart rate as reported by the strap itself. Send it by email, in a message or print it. EVERYTHING STAYS ON YOUR PHONE No account, no server, no ads. Recordings are stored only on your iPhone, and we cannot see them. One-time purchase, no subscription. APPLE WATCH TOO If you have an Apple Watch with the ECG app, you can view and share the watch’s ECG recordings in ECG Catch. IMPORTANT ECG Catch does not interpret the ECG, makes no diagnosis and gives no alerts about your heart rhythm. The app is not a medical device. If you have symptoms from your heart, contact a doctor. With chest pain, shortness of breath or fainting, call your local emergency number. Requires a Polar H10 chest strap (sold separately).
