Drop in any photo
iPhone HEIC converts automatically, and the date each photo was taken is pulled straight from the image — even for pics from months ago.
IronProof turns your progress photos into ironclad proof — a timeline of your transformation with your weight and measurements on every shot, synced across all your devices.
You're putting in the work. But if you can't see the change, it's easy to believe there isn't any.
Water weight, muscle gain, a salty meal — the number bounces around while your body quietly transforms. One number can't show recomposition.
Your progress pics are buried between screenshots and memes. Finding January's photo to compare against today? Good luck.
Daily change is invisible to your own eyes. Without side-by-side comparisons, months of hard work can feel like nothing happened.
Progress you can't see is motivation you don't get. Fix that.
Drag the slider. This is the moment IronProof is built for — seeing exactly how far you've come.
Every comparison shows time elapsed and exactly what changed — weight, measurements, all of it.
Everything you need to document your transformation. Nothing you don't.
iPhone HEIC converts automatically, and the date each photo was taken is pulled straight from the image — even for pics from months ago.
Weight, waist, chest, arms — or any custom measurement you care about — overlaid right on the photo. Imperial or metric, your call.
Photos in chronological order with "X days later" markers, so you see the arc of your transformation — not just scattered snapshots.
Weight and measurement deltas are calculated between photos automatically. Down 13 pounds? You'll see it the second you open the app.
Separate galleries for your cut, your bulk, competition prep, or specific body parts. Keep every journey organized on its own timeline.

Scroll your timeline, compare any two moments, and see exactly what your consistency bought you. Iron doesn't lie.
Watch the definition emerge week by week while the scale plays games.
Track measurements alongside photos and prove the mass is going where you want it.
