Save consistent check-ins, compare any two scans, and understand body-fat direction, muscle-group changes, physique-score movement, and what to focus on next.
A dated history of saved scans
Range-based body-fat direction over time
Visible muscle-group deltas between check-ins
Physique-score changes with contributing signals
Next-step focus areas from the latest comparison
A useful progress photo app does more than store dated gym progress photos. LeanLens connects each check-in to a range-based body-fat trend, visible muscle-group changes, physique-score context, and next-step focus areas so you can understand direction without over-reading one photo.
A dated history of saved scans
Range-based body-fat direction over time
Visible muscle-group deltas between check-ins
Save consistent check-ins, compare any two scans, and understand body-fat direction, muscle-group changes, physique-score movement, and what to focus on next.
Each saved scan connects its date and photos to body-fat range, physique score, and muscle scores. The value is not storage alone—it is a consistent record that makes visible direction easier to understand.
Compare any two check-ins with body-fat direction and muscle deltas beneath the photos. Repeatable setup matters more than dramatic lighting or posing.
Scan on a useful cadence, compare like with like, and let the trend guide the next focus area. A single noisy check-in should never overrule the longer pattern.



Privacy and honesty aren't features we bolted on; they shape how the product works.
One purpose: creating your results. Your photos are shared only with the providers needed to create or store them. Guest scans auto-delete; sign in and you can delete your saved photos and results anytime.
Ranges over false precision. No body-shaming mechanics, ever. Results describe, they don't judge. And nothing about your body is used to pressure you.
Free includes an estimated body-fat range, confidence, summary, visible scores, photo-quality guidance, core detail for every available Muscle Balance result, and a limited focus view. Pro unlocks muscle history, bilateral and training-plan detail, deeper trends, strategy, and comparisons.
Free accounts can scan again after a short wait. Pro removes the wait and unlocks full results, trends, and comparisons.
A collage places two images together. A progress photo app adds dated check-ins so you can revisit the original context and compare gym progress photos over time. LeanLens connects saved analysis history with physique context; a flattering before-and-after pair alone does not show whether the lighting, pose or training period was comparable.
Weekly or every two weeks is usually enough. Consistency matters more than frequency.
Keep lighting, camera height, distance, clothing, pose, and time of day as similar as practical.
Saved history supports comparisons so you can inspect a meaningful interval rather than only the most recent pair.
No. It connects photos to range-based composition trends, muscle-group changes, and practical context.
