The best body scan apps in 2026
3D scanners, AI photo scanners and progress trackers: what each is good for, which work on Android, and how much to trust a single scan.
Short answer
For a one-off 3D body scan, MeThreeSixty (iPhone and Android) or ZOZOFIT. For tracking body fat over time, ProgressLens: it reads matched photos plus your tape measurements, so the estimate is steady, and tells you what changed and whether to cut or bulk. Spren, trackBod, Recomp AI and GainFrame are iPhone-only.
Disclosure: we make ProgressLens. Details about other apps come from their own store listings and websites as of November 2026; prices and features change, so check the listing before you pay. We name each app’s weaknesses and our own.
