Worth considering for calorie tracking with fasting tools.
Yazio has not paid to appear here and there is no affiliate link on this page. Every fact below was read off filecontent.yazio.com, apps.apple.com, help.yazio.com on 7 October 2026. This is a documentary review of published information rather than a hands-on test, and it has not been clinically reviewed.
Ratings and review signals
The storefront score, its full sample size, and any unusually useful critical review. These are third-party signals, not our verdict.
Yazio combines calorie and macro logging, barcode scanning, fasting schedules, recipes, activity syncing, and paid planning tools. It runs on iOS and Android in 20 languages.
The full ledger
15 fields. Every one resolves to a value, a qualified answer, not offered, not disclosed, or not verified. None is left blank, and none is filled from a third party unless its note says so.
- Free tier
- Yes
Yazio's official fact sheet describes a freemium product with core features available free.
- Barcode scanning
- free core feature
The fact sheet and App Store present barcode scanning as a core calorie-counter feature. Editing public foods is limited to Pro.
- Data export
- Not verified
Health-platform syncing is documented, but a complete self-serve diary export was not found.
- Adaptive targets
- Not verified
The product personalizes calorie goals, but no first-party page establishes adjustment from measured intake against weight trend.
- Micronutrients
- Tracked and synced to Apple Health; in-depth analysis is paid
Yazio sends macro and micronutrient data to Apple Health but does not publish a nutrient count.
- Price per month
- $11.90 listed in the US App Store
Apple lists a YAZIO PRO purchase at $11.90 but does not attach a billing term. The company sells three-, six-, and twelve-month plans rather than a clearly published month-to-month plan.
- Price per year
- $23.90 or $47.90 in the US App Store
Both amounts are simultaneously listed for 12 months. Confirm the paywall offer shown to your account.
- Claimed database size
- 4 million+ searchable items
The current US App Store separately claims 4 million+ searchable items and 95% coverage of food items. Both are vendor claims rather than an independently audited database count.
- Macro tracking
- free core tracking; advanced analysis paid
Calorie and macro tracking are core features, while deeper food analysis and custom planning are promoted under Pro.
- Recipe import
- Not verified
Yazio publishes a large recipe library but no URL recipe-import feature was found.
- Photo logging
- paid
Yazio's current help center says its AI Calorie Tracking feature lets Pro members photograph a meal, then edit the estimated ingredients, portions, and nutrition before saving.
- Platforms
- iOS, iPadOS, Android, Apple Watch
The App Store and official fact sheet establish mobile availability; no web diary is advertised.
- Device syncing
- Apple Health, Apple Watch, Health Connect, Google Fit, Samsung Health, Huawei Health, Fitbit, Garmin
Named across the official terms, help center and App Store.
- Founded
- 2014
YAZIO's current official fact sheet says the web project began in 2008 and YAZIO GmbH was founded in April 2014 by Sebastian Weber and Florian Weißenstein.
- Ownership
- YAZIO GmbH
Named as the US App Store seller and in the company's terms.
The verdict
A credible calorie counter for people who also want fasting tools. Pricing is unusually hard to pin down because Apple's current purchase list shows several amounts for the same term.
Best for: People who want calorie tracking and intermittent fasting in one app.
Flaws but not dealbreakers
The live purchase list contains duplicate annual plans at different prices, current database claims conflict in form, and complete self-serve export remains undocumented.
What was sourced
Every cell in the ledger above marked as a value or as a qualified answer was read off one of the 5 pages listed under sources, on . This confirms that the vendor published the claim; it does not independently prove the claim true. Nothing was taken from a review aggregator, an affiliate roundup or a third-party blog.
Nobody on this team installed Yazio, subscribed to it, logged a meal in it or contacted it. What is above is what the company is willing to put in writing on its own properties, which is a narrower claim than whether the app works well.
What was not verified
4 things could not be confirmed from a primary source. They are listed here rather than filled with a plausible value. If you have first-hand information on any of them, the corrections address is in the footer.
