LeanLens and MeThreeSixty: first-party evidence reviewed 23 September 2026
| Decision | LeanLens | MeThreeSixty |
|---|---|---|
| Input | One to four selected physique photos for a visual estimate; no depth scan or tape measurement. | Guided phone images for a reconstructed 3D scan. |
| Output | Estimated body-fat range, confidence context, visible muscle and symmetry guidance. | 3D avatar, estimated dimensions and body-composition history, as advertised. |
| Platform | Browser guest entry and official iPhone app; Android users can use the browser. | Android listing reviewed; verify the current iPhone listing and supported handset. |
| Privacy | Source uploads, optional saved history and deletion have separate rules in the LeanLens Privacy Policy. | Check the official policy for image processing, scan history, export and deletion. |
| Price and access | Guest web scan and recurring eligible Free scans; saved history and report depth depend on the displayed plan. | The official site places full scan history in Premium; current regional checkout price was not verified. |
Avatar measurements and photo interpretation answer different questions
MeThreeSixty presents smartphone 3D scanning and progress visualization, powered by Size Stream. Its official site places full scan history among Premium benefits. Its Google Play listing establishes an Android option; LeanLens’s native Android app remains a waitlist rather than a downloadable alternative.
LeanLens analyzes photographs for estimated body fat and physique context. It is not a substitute for a full circumference map or a virtual fitting system. If your central question is how your waist measurement changed, an app designed around body dimensions deserves consideration before a physique score.
A practical comparison protocol
Use the same week for your first observations, but do not expect two different methods to return identical body-fat percentages. Repeat each method under its own recommended setup. Compare whether each workflow is repeatable and whether the output answers your original question.
For example, someone choosing clothing sizes should prioritize measurement definitions and garment compatibility. Someone reviewing gym progress may prioritize consistent photographs, strength records and useful interpretation. An avatar looking smoother or more detailed does not establish measurement validity.

History, compatibility and paid access
Before making MeThreeSixty your only archive, check which historical scans remain accessible without Premium and what export options are available in your installed version. Before choosing LeanLens, check the distinction between the browser result and saved app history. These are access questions, not body-analysis accuracy questions.
Check the store listing for your country and handset. We have not run a cross-device scan test or independently verified current checkout prices. Treat the vendor links as a starting point for checking the offer, not a promise that every feature is free on every platform.
Limits and safety
Photo estimates and consumer body-composition outputs are not medical diagnoses. Product availability and paid access can change; confirm the current offer before subscribing.
FAQ
Is this a hands-on review?
No. This is a dated comparison of official product information, with editorial selection guidance. It does not report a device test or rank accuracy.
Which app is more accurate?
This comparison cannot establish that. A fair accuracy claim needs a defined outcome, reference method, representative participants and a reproducible test.
Is LeanLens a replacement for every feature?
No. Check input method, platform, history, measurements and paid access against your own requirements before switching.
