AI calorie & macro tracker
Point your camera at the plate. Dietz names the dish, breaks it into items, and fills in calories, protein, carbs and fat — before you've put your fork down.
Free to start · iPhone & Android · 25 languages
Your height, weight, goal weight and how fast you want to get there set one number: today's calorie target. Everything else on the home screen counts toward it.
About Dietz
Most people quit a calorie app in the first week — not because they stopped caring, but because searching a database for "chicken thigh, roasted, skin removed" three times a day is a chore. Dietz removes the chore. You take one photo and the log fills itself in.
Features
Snap
Dietz names the dish, tags every item it can see, and totals the calories and macros. Tap any label to correct it before you save.
Describe
No photo? Type "two eggs, sourdough and half an avocado" and get the same breakdown. Packaged food scans by barcode.
Macros
The ring on your home screen shows calories left for today; the three bars under it show how your macros are splitting out.
Workouts
Log a run, a push day or a yoga session and the calories you burned come off the day's balance automatically.
Streaks
Three quiet meal reminders a day, a streak counter, and a weekly insights view that tells you whether you're actually on track.
The process
A short setup — age, height, current and goal weight, how fast you want to move — turns into a daily calorie and macro target, plus the date you'd reach your goal at that pace.
At every meal, open the camera and snap. Review what Dietz found, adjust anything it read wrong, save. That's the whole loop.
Insights shows calories in versus out, your average day, your macro split, and whether the week landed under or over goal — so you adjust from evidence, not guesswork.
Calories remaining, macros filling up, and everything you've logged so far — one screen, no drilling.
Running, cycling, strength, HIIT or yoga — pick it, log it, and watch today's balance move.
Privacy
Your meals, weight and photos live in your own account. Nothing is published, shared with other users, or shown on a feed — there isn't one.
We don't sell your personal information to third parties, and Dietz doesn't run ads against what you eat.
Meal analysis runs through our own server, which only accepts requests from a signed-in account. API keys never ship inside the app.
Delete your account from inside the app and your log goes with it. No retention hostage-taking.
