Scan your body, get a 3D cartoon version of yourself, and lose weight by talking to Pochi, an AI coach that logs your food, weight and training for you. Your cartoon changes shape as you do.
Results vary by person. Fitoon is a wellness app, not a medical device; measurements are estimates.
How it works
Onboarding is a chat with Pochi on a cartoon stage: one question per screen, big tap-to-answer chips, voice optional.
Put your phone down, step back, and take a front and side photo. Segmentation runs on your iPhone and the photos are deleted by default.
Curtain, drumroll, TA-DA: a cute 3D cartoon you, built from your real proportions. Style the hair, eyes and outfit. About 90 seconds from hello to reveal.
Say “ramen and gyoza for lunch” or send a photo. Pochi logs the meal, your weight and your workouts, and plans the day with you. No searching, no grams.
A weekly scan shows centimeters lost even when the scale is stuck. Your cartoon slims with you, and the room fills with plants and posters as you go.
Meet Pochi
Pochi is a marshmallow with a sprout and very big eyes. It floats next to your cartoon, listens when you talk, and keeps the log so you don't have to.
Celebrates small wins loudly and treats setbacks lightly. “Ramen happens. Let's make dinner light!”
One sentence or one photo per log. Pochi matches it to a food database and never forces exact grams.
When Pochi estimates, it says so. Calories and measurements are always labelled as estimates.
Calorie floors, healthy goal limits, no extreme advice. No red warnings, no “bad food”, ever.
Pochi
listening
You: Shoyu ramen and six gyoza for lunch.
Pochi: Ramen happens! Logged shoyu ramen (1 bowl) and gyoza ×6. That's about 820 kcal and 30 g protein, as an estimate. Dinner could be grilled fish and a salad. Deal?
Lunch logged
You: Deal. Also 62.4 this morning.
Pochi: 62.4 kg saved. Your trend is down 0.3 kg this week. Nice and steady!
Shape over scale
Fitoon always shows shape and centimeters next to kilograms, because that's where real progress hides.
Water, salt and hormones swing the number by a kilo or two from day to day. People quit when it stops moving.
A weekly two-photo scan estimates waist, hip and thigh to about ±3 cm. Fat loss shows up here even on a stuck week.
No gray realistic mesh. Your progress is a cartoon slimming down, with the option to hide the weight number completely.
Scale: 68.0 kg
Scale: 68.0 kg · Waist: −2 cm
An illustrated example: same weight, visibly different shape. The mirror shows what the scale can't.

Your room
Everything opens from the room and returns to it. Tap an object, or just ask Pochi to show it. The lighting follows the real time of day.
Your progress: trend weight, waist in cm, and a Now ↔ Goal morph of your cartoon. Sparkles after every new scan.
Step in for the weekly scan. It glows on scan day, and the results are blended if a number looks implausible.
Outfits, hats, plants and posters bought with coins you earn by logging. Seasonal items for sakura, summer and New Year.
Friends' cartoons wave outside. Start challenges, cheer each other on, and earn bonus coins when a friend signs up with your invite code.
Quick weight entry, a photo of your real scale, or a sync from Apple Health. Hide the number entirely if you prefer.
Badges for first log, first scan, streaks, −5 cm waist, 10 workouts and more. Streak freeze once a week, no punishment.
