Reach your goals at your pace
Weigh in, watch the trend, and plan in holidays. The forecast shows how likely each goal is, honestly.
Everything you need, nothing you don't
Kevyt does the maths and keeps the screen calm. One Analysis section tells you plainly how you're doing and what comes next.
Forecasts, not guesses
See your trend, your weekly pace and a forecast range for every milestone, with the probability of reaching each goal on time.
Plans that fit real life
Add holidays as a pause or an expected gain. The forecast takes them into account instead of pretending life is a straight line.
A fast food diary
Thousands of foods built in, barcode scanning, your own foods and recipes, and "same as yesterday" for the days that repeat.
Log from a photo
Snap a meal or describe it. AI names the foods and estimates the amounts. Calories always come from the food list, and you confirm before anything is saved.
Meal plans and shopping lists
Weekly plans built around your tastes, allergies and calorie target, checked for protein and fibre, with one shopping list for the week.
Honest reviews
Ask for a review of your day or week. Kevyt computes the numbers and your AI writes short feedback with at most two recommendations.
Your data stays on your phone
Kevyt has no accounts and no Kevyt server. Your weight, your meals and your notes are stored on your device. If you want a backup, it goes to a cloud folder you own, not to us.
- Bring your own AIAI features use the provider you choose, with your own key, or a model you run yourself. Requests go straight from your phone to that provider.
- You see what's sentReviews send only the numbers Kevyt computed, and you can see exactly what goes out. Photos are shrunk and stripped of location data first.
- Keys stay locked awayYour API key is kept in the phone's secure storage and is never included in exports.
- Backup and sync in your own cloudKeep a daily backup in your own WebDAV folder (Nextcloud, a NAS and many storage providers) and keep your phones in step through it. Add a passphrase and everything is encrypted on your phone before it leaves.
- Leave whenever you wantExport everything to one file, or weigh-ins and the food diary to CSV. Erase everything in one step.

A note on health. Kevyt is a tracking and planning tool, not medical advice. If you set an aggressive goal, Kevyt will suggest you talk to a doctor first. Please do, especially if you have a health condition, are pregnant or breastfeeding, or have a history of disordered eating.
