| Phone photo library | Preserves camera dates when originals remain intact; matching pose and crop are manual. | Storage and sharing follow your device and cloud settings; export the original files. | Included app, while cloud-storage capacity depends on your device account. |
| ProgressCam on iPhone | The listing describes a capture overlay, imported photos, timeline and comparison views. | Check its current policy and whether your chosen export needs Pro or has a watermark. | Free with in-app purchases; Pro expands projects, photos and HD export. Exact free quotas were not established. |
| LeanLens web / iPhone | Web analysis is a current-photo result; the iPhone app supports dated check-ins and comparisons. | Read the separate upload and saved-photo rules; retain originals before any app export or deletion. | Free browser scan and recurring eligible Free scans; check the current plan for saved-history and export access. |
Choose a free archive or a free analysis
For a no-new-subscription archive, your existing photo library may be sufficient. Keep originals and dates in a dedicated album. Apple documents original-file export and optional iCloud syncing; Google documents Android backup and account storage limits. Its tradeoff is manual alignment and comparison rather than a purpose-built body tracking report.
ProgressCam’s official listing describes capture overlays, imported photos and comparison views. It reserves expanded project/photo allowances and HD export for Pro. The listing does not establish every numeric free quota, so this comparison does not invent an unlimited free tier.
Check import, comparison and export separately
Before importing months of images, try two unimportant sample photos. Check whether original dates survive, whether both photos can be aligned and whether the export has a watermark or resolution limit. Check the cancellation terms before starting any trial.
If your goal is an AI estimate rather than an archive, use the photo calculator. For recurring LeanLens check-ins, review the progress app and current access. Do not assume a free browser result unlocks unlimited app history.

Keep control of your originals
Keep a copy outside the comparison app and understand whether your phone library syncs to a cloud account. A private album name does not by itself control backup or sharing. Review deletion and export controls before uploading body photos.
This is a source-based shortlist checked September 23, 2026, not a hands-on ranking. Choose an archive for storage, a capture tool for alignment, and analysis only when interpretation is useful.
Limits and safety
LeanLens content is informational fitness guidance, not medical advice, diagnosis, or treatment. Photo-based analysis should be used for trend direction and practical next steps, not clinical decisions.
FAQ
Which progress app has no subscription?
Your existing phone photo library can support a manual archive without a new app subscription; cloud storage may still have paid limits. Verify dedicated apps’ current checkout before assuming lifetime free use.
Does free mean a free trial?
Sometimes. Check whether access expires, whether payment details are required, and which exports or comparisons remain available after the trial.
