In short
ProgressLens is a before-and-after photo app for body progress. You take your photos in the app, each one lined up with the last, and then pick any two days with the same pose to compare. You can keep the comparison private or share it as one image. It works on iPhone and Android with no account.
Fair comparisons
A great “after” starts with a fair “before”.
You can’t fix a mismatched before photo later. ProgressLens makes each new photo match the previous one, so every pair you choose is honest: same angle, same distance, same pose.

How it works
Thirty seconds a week.
No setup, no sign-up, no learning curve. Open the app, take your photo, done.

Snap your photo
Front, side and back. Your last photo shows faintly on the screen, so you stand in the same spot every time.

Add a number or two
Weight and waist take ten seconds. Skip them if you’d rather not. The photos do the talking.

See the difference
Pick any two days and flip between them. That’s the moment it clicks.
Whatever you’re working on
Made for your journey.
FAQ
Questions, answered
How do I make a before and after photo?
In ProgressLens, choose two photos of the same pose and share. For photos you already have, use the free before and after maker.
Can I share it?
Yes, as a single image, only when you choose. Free shares carry a small watermark; Pro removes it.
Are my photos private?
Yes. They stay inside the app on your phone: not in your photo gallery, not in the cloud, and there’s no account. Nobody sees them unless you share.
Is it free?
Free to download and try, with every feature. Your first 10 check-ins are free, then one payment unlocks unlimited check-ins forever. No subscription.
Does it work on iPhone and Android?
Yes, on iPhone and iPad (iOS 17 or later) and Android (Android 7.0 or later).
