In short
For 75 Hard, take your daily progress picture at the same time and place, ideally each morning, and compare day 1 with days 25, 50 and 75. ProgressLens shows your previous photo faintly on the camera so every daily photo lines up, reminds you each day, and keeps the photos private.
Daily, without the mess
75 photos. One clean timeline.
Every day gets a mark on your calendar. Filter to front photos and compare day 1 with today in two taps. Set a daily reminder so you never miss one and have to start over.

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
Is ProgressLens free for 75 Hard?
The first 10 days are free. A full challenge needs Pro: one payment, not a subscription.
Does it track the other 75 Hard tasks?
No, just your photos and measurements. Use a habit tracker for the rest.
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.
Does it work on iPhone and Android?
Yes, on iPhone and iPad (iOS 17 or later) and Android (Android 7.0 or later).
