Why we picked it
Serious lifters and data-driven users who want the closest thing to a clinic body-composition scan at home, with heart-health metrics in the same app
What to know before you buy
At roughly $500 it costs 4-10x a typical smart scale, and like every BIA device its segmental fat/muscle numbers are estimates best used for trends, not absolute values; some owners report app sync hiccups
