Amazfit Active 3 Premium vs Withings ScanWatch 2: which should you buy?
Get the Withings ScanWatch 2. It is the better watch for health and sleep, and it can record an ECG that checks for atrial fibrillation, which the Amazfit Active 3 Premium cannot. It also looks like a classic watch, so it works at a desk and at dinner.
Who should get the Withings ScanWatch 2
Get the ScanWatch 2 if health comes first and you want a watch that looks like a watch. Withings lets you record an ECG that checks for atrial fibrillation by resting a finger on the bezel, and it tracks sleep stages and overnight heart rate variability. It works with an iPhone and with an Android phone, and its battery lasts weeks.
Who should get the Amazfit Active 3 Premium
Get the Active 3 Premium if you want a light everyday watch that takes running seriously. Amazfit gives it built-in running workouts, coached plans from a 5K to a marathon, and running power, plus heart rate, blood oxygen, skin temperature and sleep tracking with no subscription. It also carries free offline maps with turn-by-turn directions. On an iPhone it works with limits, so some features that need deeper phone access stay on Android.
The differences that matter
The Active 3 Premium is the better training watch, with coached running plans, running power and offline maps. If you train for races, it does more.
Both are fine for swimming. Both track sleep. The split is health checks against training tools.
