YAZIO is the tracker to reach for when intermittent fasting is part of your plan. It keeps a calorie target and a fasting window in one clean app, so a 16:8 schedule does not need a second subscription, and PRO, at about $48 a year as of mid-2026, adds full macros, more than ten guided fasting programs, 2,900-plus recipes, and AI photo logging. The catch is the free tier, and it is a real one: YAZIO shows total calories for free but hides the protein, carb, and fat breakdown, so anyone who tracks macros is pushed toward PRO. The food database is smaller than MyFitnessPal's as well. Our verdict: a strong pick for fasters who want one app for both jobs, and a weaker one if free macros or the deepest database are what you care about.
What YAZIO is
YAZIO is a German-built calorie counter that grew popular across Europe and now competes globally. Its distinguishing idea is combining two habits people usually run in separate apps: calorie tracking and intermittent fasting. The design is friendly and modern, and the fasting integration is the reason most users choose it over a general-purpose tracker.
How tracking and fasting work together
You set a calorie goal and log meals by search, barcode, or, on PRO, an AI photo. The fasting timer runs alongside the log, so you see your eating window and your calorie budget in one place. PRO expands the fasting side into structured programs like 16:8 and 5:2 and adds a recipe library and meal plans. To set the calorie target it starts from, our free TDEE calculator and macro calculator give you the numbers without a signup.
What YAZIO costs as of mid-2026
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | Calories, barcode, one basic fasting timer — no macro breakdown |
| PRO monthly | $6.99/mo | Full macros, fasting programs, recipes, AI photo logging |
| PRO annual | About $47.90/yr | Same as monthly, often discounted further via promotions |
YAZIO runs frequent promotions, so the annual price is sometimes lower than the sticker, around $38 during a common 20% offer. Check the in-app price before committing.
What YAZIO does well
- Fasting and calories in one app, which most trackers split or paywall.
- Clean, friendly design that is easy to start with.
- Large recipe library and guided fasting programs on PRO.
- Barcode scanning and a basic fasting timer are free.
Where YAZIO falls short
- No free macros. The free tier shows calories only, so macro tracking means paying for PRO.
- Smaller database. Coverage trails MyFitnessPal, especially for restaurant and regional foods.
- PRO nudges. The free experience pushes toward the paid tier fairly often.
YAZIO vs Joules
Full disclosure: Joules is our app, so treat this as a competitor comparison. Give YAZIO its due, its library of guided fasting programs is deeper and more structured than what Joules offers. Joules includes an intermittent fasting timer too, but its real bet is logging speed: photograph the plate, confirm or correct the AI read in a tap, and your macro rings fill in right there as part of the daily view. Around that sit one daily health score with reasons, habit streaks, and Apple Health and Google Fit sync, on a calm ad-free screen. The download page has the details.
Who YAZIO fits
YAZIO fits people who combine intermittent fasting with a calorie goal and want one app for both. It fits badly if you want macros without paying, or the largest possible database.
