Amazfit vs WHOOP

QUICK VERDICT
The choice is mostly about workflow and budget. If you already train by strain numbers and you like the no-display, always-worn philosophy, WHOOP earns its monthly fee through a tight recovery and strain model. If price-to-spec matters or you want a screen with GPS, Amazfit gives you more signals and zero monthly fees. The two share daily wrist signals (HR, HRV, sleep) but pull apart on philosophy more than on technology.
