About ProgressLens
ProgressLens is a small, independent app made by one developer who wanted progress photos that actually compare, without a subscription or an account.
Short answer
ProgressLens is a progress photo app for iPhone and Android. It helps you take front, side and back photos that line up with your last ones, using a faint copy of your previous photo on the camera, and keeps them next to your weight and body measurements. You can compare any two days side by side. Photos stay private on your phone, there’s no account, and it’s free to try with a one-time upgrade instead of a subscription.

Why ProgressLens exists
Progress photos in a camera roll are almost useless: taken at different distances, in different light, mixed in with everything else, and synced to places you don’t want them. ProgressLens turns them into a private journal where every photo matches the last.
It doesn’t try to be a coach. There’s no AI rating your body and no diet plan. It shows you what changed, honestly, and works with whatever plan you follow.
Who makes it
ProgressLens is built by David Pintarič and published by Pod27, an independent studio that also makes C for Calories, a free AI calorie counter.
How we write guides and comparisons
Guides cite public health sources where numbers matter. Comparisons with other apps use what each developer says on its store listing or website, dated, and say so when we couldn’t verify something. If something about another app is out of date, email us and we’ll fix it.
