ECG Tracker+ HRV, QTc & Reader
by Artur Teodorowicz
Description
Your Apple Watch ECGs, analyzed on your iPhone by models we trained ourselves. 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.

What's new (v1.1.1)
We fixed several bugs that were affecting our new machine learning-based ECG analysis, so it now runs more accurately and reliably.
