ProgressLens vs ZOZOFIT
A one-off scan or rating, or a running read of your own progress? Here’s how they differ.
Short answer
ZOZOFIT a 3D body scanner focused on circumference measurements rather than photos. ProgressLens is an AI progress photo app for iPhone and Android: it reads your photos together with your tape measurements, so its body-fat range stays steady, and every Progress Report says what changed, whether you’re losing fat or muscle, and whether to cut, lean bulk, recomp or maintain. Pick ZOZOFIT for 3D circumference measurements from a body scan; pick ProgressLens to track whether it’s working and what to do next, on any phone, in 11 languages.

Choose ZOZOFIT if…
you want 3D circumference measurements from a body scan.
Choose ProgressLens if…
you want to know whether your progress is working and what to do next: a steady body-fat range from photos plus tape, what changed since last time, a fat vs muscle check, and a clear cut or bulk verdict, on iPhone or Android, in your language, without an account.
Why photos plus tape beat a single scan
Photo-based body fat estimates move with lighting, pump, pose and clothing, so two scans a week apart can disagree by several points. In our analysis of Reddit posts, people quoting estimates from different AIs saw gaps of 2 to 8 points. ProgressLens anchors the photo read with the US Navy tape formula and your history, and the same photos always give the same result.
