Photos are analyzed to build your forecast, then deleted from our servers within 24 hours. Your weekly progress photos stay on your phone.
YOUR PERSONAL FORECAST
Upload one photo. Day90 predicts your body at 30, 60 and 90 days of consistent training, then tracks whether you get there.
These are estimates. What you eat, how you sleep and how consistently you show up decide the outcome.
Your first selfie builds the forecast. Every progress photo after rebuilds it, so the day-90 you on your screen is never a guess from week one. It's a projection from today.
One photo. Taken in your room, in 60 seconds. Analyzed and deleted from our servers after processing.
Your body at day 0, 30, 60 and 90. The forecast is built from your own frame and starting point, so day 30 looks like you after four weeks of work, and day 90 looks like you after twelve.
Upload a progress photo every 2-3 days. We track prediction vs. reality and regenerate your forecast from your newest photo. Motivation dipping? Open the app, create a fresh look at the body you are building. It is always one tap away.
YOUR PERSONAL FORECAST
Upload one photo. The AI forecasts the body you reach at every stop from day 30 to day 90, built from your own frame, not a stock model.
YOUR PROGRESS PHOTOS
The before/after slider holds both timelines: what the AI said, what your camera shows. Every two or three days you add a progress photo. It sits right next to the prediction, so you always know where you stand: ahead, behind, or on track.
YOUR CAMERA 
PREDICTION THE HABIT ENGINE
And it's always current. After every photo you upload, your forecast regenerates. The future you on your lock-screen widget isn't the one predicted a month ago. It's the one your last workout earned. Bad day? Generate a fresh look at day 90 and get back in.
Miss a week and the far stops grey out. One upload turns them back on.
// HOME & LOCK SCREEN
The widget shows your current day, your streak and your next photo date, right on your home screen, every time you pick up your phone.

YOUR PHOTOS STAY YOURS
Your photos are used for one thing: generating and tracking your prediction. They are processed on EU infrastructure, deleted from our servers within 24 hours, and we never use them to train AI models. Here is exactly what happens to a photo you take.

FAQ
It's an estimate built from your photos and training plan, based on typical results for natural training. What you eat, how you sleep and how consistently you show up decide the outcome.
Yes. That's the point. Any time motivation drops, open the app and generate a current forecast: day 30, 60 or 90 from today's body, not from the day you signed up. Check it before the workouts you almost skip.
