AI coach
A coach that knows your numbers
It sees your food, weight, steps, fasting and vitamins, does the maths on your own data and remembers what matters: night shifts, training days, a family to feed.
Is my pace OK?
Your weight isn’t stuck — the trend is going down: −0.8 kg in 3 weeks. Protein averages 81 g against a 133 g target — top it up and you’ll stay full longer.

Can I use 17 Fit for free?
Yes. The diary, plan, weight, measurements, reports and challenges are free with no limits. The Basic plan has a little AI every day too; Pro raises the limits, and Pro+ adds an unlimited coach.
Do I need to sign up?
No. The account is anonymous and tied to your phone — no name, e-mail or phone number. Reinstall on the same phone and your data comes back by itself.
How accurate are calories from a photo?
The AI recognises the dishes and estimates the grams, and you can always adjust them — the diary trusts your numbers. Shoot the whole plate in daylight; for packaged food, a barcode or label scan is more precise.
Which devices does 17 Fit run on?
17 Fit is an iPhone app; get it on the App Store. The app speaks eight languages: English, Ukrainian, German, Spanish, French, Italian, Romanian and Polish.
Does it work with Apple Health?
Yes: steps, active calories and weight sync with Apple Health.
How do I cancel a subscription?
On your iPhone: Settings → your name → Subscriptions. The plan keeps working until the end of the paid period. Refunds go through Apple at reportaproblem.apple.com.
How do I delete my data?
Profile → Privacy and data: turn sync off, export everything to a file or erase the server copy. To delete the account entirely, write to us.
