- 24/7 stress index without monthly fees
Amazfit vs Garmin
Amazfit reads 16/27 signals from a budget Zepp OS watch and ships 24/7 stress out of the box. Garmin reads 20/27 from a far broader athletic platform — Body Battery, training load, ECG, AFib screening, floors climbed — and uses manual GDPR upload until OAuth opens.

QUICK VERDICT
If price is the binding constraint and you want most of the daily-health signal stack today, Amazfit is the better budget pick — same OAuth setup as Garmin's eventual one, and 24/7 stress works out of the box. If Body Battery, training load, ECG with AFib screening, or floors climbed matter to you, Garmin is the more complete athletic watch even with the weekly GDPR ZIP upload until its OAuth flips on.

FAQ
Frequently asked questions
Should I choose Amazfit or Garmin?
For most people it is one or the other. Both are daily-wear devices that track the same core things, heart rate, sleep and activity, so wearing both is redundant. Use the matrix above to pick the one that wins the categories you care about.
Which one tracks more health signals?
Amazfit tracks 16 of the 27 signals I compare, Garmin tracks 20. The matrix above breaks it down by category, and they often win different categories.
Is it worth switching from Amazfit to Garmin?
Only if Garmin wins the categories you actually care about. If you already own Amazfit and it covers your main goal, the upgrade is rarely worth it. The matrix above shows exactly what changes.
