Amazfit vs Withings
Amazfit reads 16/27 signals from the wrist — heart, sleep, activity, 24/7 stress. Withings reads 20/27 from a clinical scale, BP monitor, and watch — body composition, blood pressure, sleep apnea screening, AFib, body temperature. They share the daily heart/sleep/activity baseline, but their specialties barely overlap.

QUICK VERDICT
These two are deeply complementary, not competitors. Amazfit covers the daily wrist signal stack — HR, HRV, sleep, 24/7 stress — at the lowest price in this comparison. Withings adds everything a watch can't physically measure: muscle mass, hydration, blood pressure, sleep apnea, ECG with AFib. Together they're the cheapest way to reach a really wide signal coverage in MyBodyAI.

Yes, and they complement each other. Withings measures what a watch cannot on its own, body composition from a smart scale, blood pressure, and on some models an ECG. Many people keep Amazfit for daily tracking and add a Withings device for the rest.
Which one tracks more health signals?
Amazfit tracks 16 of the 27 signals I compare, Withings tracks 20. The matrix above breaks it down by category, and they often win different categories.
Which one should I get first?
Start with whichever covers your main goal. For daily heart rate, sleep and workouts, go with Amazfit. For weight, body composition and blood pressure, go with Withings. You can add the other later.
