## What is Stronger?

Upload a photo and see how another body would look on you. Stronger uses generative AI
to hand your own photo back with more mass, sharper definition or a leaner shape — and
lets you compare before and after by dragging across the same image.

NINE LOOKS, ONE TAP
Bulk, Cut and Lean, each in three levels. All of them sit on the same screen: pick one
and the image is generated right there, without switching screens or filling in forms.
Not convinced? Tap another one.

BEFORE AND AFTER, ON THE SAME PHOTO
The slider runs across the image under your finger. No collages, no frames: the same
photo, split wherever you want it.

YOUR RESULTS, ON YOUR PHONE
The app keeps your last 30 results in its own gallery, on the phone itself, and you can
reopen any of them in the comparator whenever you like; once you reach 30, the oldest
one makes room for the new one. You can delete them all at once from Settings.

WHAT WE DO WITH YOUR PHOTO, NO SMALL PRINT
Your photo leaves your phone encrypted, goes through an automatic safety check at Google,
then to our AI provider to generate the result, and the result goes through that same
check before you see it. It is never stored on Stronger's servers. Before your first upload we tell
you exactly who processes the image and under whose policies. No accounts, no sign-up,
no ads.

EVERY RESULT IS MARKED AS AI
Because EU law requires it and because it is the honest thing to do. On the free tier
the result also carries the app's visible mark. And there is a report button right on
the result screen.

FREE AND PRO
Free: 3 generations a day, with a 10-second wait between them, and no saving or
sharing. Pro: up to 20 a day and 150 a month under fair use, saving and sharing, and no
waiting. The
subscription is billed monthly or yearly and comes with no free trial: the price in
your own currency is right there on the subscription screen, before you decide.

SIX LANGUAGES
English, Spanish, French, German, Italian and Portuguese.

18+ only. Upload photos of yourself, or of adults who have given you permission.
Results are AI-generated fantasy images for entertainment: they predict no real physical
change, and the app gives no medical, fitness or nutrition advice.
