If you’ve seen the Amazfit Active 2 Round (already reviewed here), the Square version shares most of the same tech in a different body. The square AMOLED screen gives you more screen real estate for data, and the stainless steel frame makes it feel more premium on the wrist.

For recovery tracking, the Active 2 Square hits the marks that matter. Sleep staging is solid, it reliably distinguishes between deep and REM cycles, and the morning readiness score gives you a quick green/yellow/red on whether you should push hard or back off. HRV trends over time are where this gets useful: after a couple weeks, you start seeing how training load, alcohol, and late nights affect your baseline.

The square screen is a real plus for data-heavy watch faces. You can fit workout stats, HRV, sleep score, and step count on one face without squinting. The always-on display works well in bright sunlight too.

Battery life runs about 10 days with normal use, or around 5 with heavy GPS usage. Not class-leading, but respectable for a watch with an always-on AMOLED display. Charging takes about 2 hours from empty.
