Hi which series gave the EKG option? What’s the biggest difference between the 4, 5 & 6?
The ECG app can record your heartbeat and rhythm using the electrical heart sensor on Apple Watch Series 4, Series 5, Series 6, or Series 7* and then check the recording for atrial fibrillation (AFib), a form of irregular rhythm.
You might have a tough time finding any of those series new since the series 7 just came out:
