ONE PHOTO BUILDS THE FORECAST
You've wondered what you'd look like if you actually stuck with it. Day90 answers with one photo: your body at day 30, 60 and 90 of consistent training. Then it tracks whether you get there.
These are estimates. Your training, food and sleep decide what becomes real.
BUILT FOR WEEK 3
Week 3 is where most attempts die. The work is real, the change is still invisible, and quitting starts to feel reasonable. Day 0 next to your latest photo settles it in one glance.
LATEST PHOTO 
DAY 0 HOW IT WORKS
The first photo gives you the target. Every progress photo after that updates it, so the body on screen keeps moving with you.
Take one photo in about a minute. It builds your first forecast and comes off our servers within 24 hours.
See your body at day 30, 45, 60, 75 and 90. Each stop starts from your frame and your starting point.
Add a photo every third day. Each one rebuilds the whole forecast from your newest body, so you always see the next 90 days from where you stand.
WHAT THE FORECAST SHOWS
Every stop is built from your own frame. Day 30 looks like you after four weeks of work, and day 90 looks like you after twelve.
YOUR PHOTO OPENS IT
ANY STARTING POINT
Three different men, three different starting points. The forecast starts from the photo, so day 90 looks like the man who took it.

DAY 90 · FORECAST FOR THE HARD DAYS
Day90 asks for three taps a day: trained, ate clean, no alcohol. One photo every third day. Every green box is a day you showed up; a missed day stays grey — and the next box is still yours to fill.
Bars: training · eat clean · no alcohol
Check in every day, add a photo every third — and the forecast keeps showing the next 90 days from your newest photo.
REAL SCREENS
Real screenshots from the current build. Each screen shows where you stand and what comes next.
HOME AND LOCK SCREEN
Your day count, next photo date and current target sit on your home and lock screen. They catch you on the days you start talking yourself out of it.

ON YOUR WRIST
Trained, ate clean, no alcohol — three taps on the Apple Watch, and your phone syncs the moment you tap. A watch-face complication keeps today's score in view between sets.
PAIR UP
Pair up with the people you train with, or a friend who is starting too. Partners see your day count, streak and consistency boxes — your photos stay on your phone. Someone notices when you go quiet.
