Amazfit
Pick Amazfit if
- Price is the binding constraint
- Long battery on a consumer watch matters
- 24/7 stress index without monthly fees
Amazfit vs Garmin
Amazfit reads 21/33 signals from a budget Zepp OS watch and ships 24/7 stress out of the box. Garmin reads 27/33 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 on hardware, but it has no MyBodyAI integration yet, so nothing from it reaches the app; Garmin's data does, through the export upload. 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.

Verified against vendor developer documentation and MyBodyAI backend code. This counts what a brand's API exposes, which is not the same question as what one device measures: the device catalog scores each model's own hardware, so its numbers differ.

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 21 of the 33 signals I compare, Garmin tracks 27. 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.
How did you compare Amazfit and Garmin?
From each brand's official spec sheets and support pages, cross-checked against independent hands-on reviews (DC Rainmaker, the5krunner, Tom's Guide). Signal-level edge cases are noted in the matrix, not hidden behind a single check mark.

OPTIONAL — IF YOU WANT MORE
Want one place that merges both feeds?
MyBodyAI is what I build with these signals — it pulls from any combination of the brands above and derives Biological Age and 12 health indices from the raw numbers. Free to try, no card. It's optional — the comparison above stands on its own.
