No cloud. No accounts. No data leaves the device. ECG Tracker+ imports your ECG recordings from the Health app and gives you a deeper read than the watch alone — sharper QT measurements, clearer rhythm context, and findings highlighted right on the waveform. ——————————— OUR OWN ON-DEVICE ECG MODELS We spent weeks training a family of in-house ECG models on large, expert-annotated public datasets. Tuned to run fully on-device by harnessing the power of Apple Silicon, they bring sharper P, Q, R, S, T placement and cleaner QT measurements — especially on noisy Apple Watch traces where the previous pipeline used to back off. NEW EVENTS WE NOW FLAG • Bigeminy and trigeminy — repeating premature-beat patterns • Possible VT run — three or more consecutive premature ventricular beats • Wide QRS / possible bundle branch block — when QRS duration ≥120 ms • T-wave inversion — negative T-wave polarity on the representative beat Every finding appears on the library card and is highlighted directly on the waveform. MEASUREMENTS THAT MATTER • HRV — rMSSD and SDNN, with trend comparisons over weeks and months • QT and QTc — multiple correction formulas, manual override when you need it • QRS duration, PR interval, RR interval • Heart rate ranges and signal quality scoring TRENDS YOU CAN ACTUALLY READ Compare the last 30 days against the previous period. Spot drifts in heart rate, HRV, and QTc at a glance. Tap any data point to jump straight to that recording. EVERYTHING STAYS ON YOUR IPHONE All analysis runs on-device. No cloud, no servers, no accounts. Your ECGs never leave your iPhone. Delete the app and the data goes with it. EXPORT CLEAN PDF REPORTS Share a clinically-formatted PDF of any recording with your doctor — waveform, measurements, notes, and symptom tags all in one document. ——————————— Download ECG Tracker+ and get more out of every ECG your Apple Watch records. ECG Tracker+ is an informational measurement tool and is not a medical device. It does not provide medical advice, diagnosis, or treatment.
