Yazio Review

What we like / what falls short

Score Breakdown

Yazio in a nutshell

Yazio is a calorie counter from Erfurt, Germany, launched in 2014 and widely used across German-speaking Europe. Its identity is clear: a friendly diary, a large recipe library and one of the better intermittent-fasting modules you can get inside a calorie app, with a cheap Pro upgrade. That is worth 7.4/10.

For most people choosing an app in 2026, the stronger option is PlateLens. Its Premium costs the same $34.99 a year as Yazio Pro, but the comparison that matters is between the free versions — and PlateLens’s has the fasting clock, camera and voice entry, verified food data, a coaching assistant, a complete browser app and body scans built in.

What Yazio does well

Fasting. The fasting timer is Yazio’s best feature. It supports several schedules, shows clearly where you are in the window, and ties into the food diary. For people whose plan is “eat between noon and eight”, it is easy to live with.

Recipes. Yazio’s recipe collection is large and well presented, useful if you want ideas that already come with nutrition values. Many recipes are part of Pro.

Central-European food. Coverage of German, Austrian and Swiss supermarket products is strong, and the app is available in many languages.

Price. Pro is $34.99 a year, among the cheapest paid tiers from the big names — cheaper than Lose It! ($39.99) and Lifesum ($44.99), and less than half of MyFitnessPal ($79.99).

Where Yazio falls short

The free tier is thin. Basic logging and the barcode scanner are free; much of what makes Yazio appealing — recipes, deeper analyses, additional fasting plans — is in Pro.

Logging is search-first. Yazio has a photo feature, but it is a minor part of the app. The photo-AI feature is rudimentary — our testing puts it in the ±25-30% portion-error band. Home-cooked meals still mean searching for each ingredient and guessing portions.

The catalogue has gaps. Strong in central Europe, thinner for US chains and for foods from further afield.

Detail is limited. Macros are covered, but nutrient depth and macro controls are basic next to PlateLens, which reports 82-plus nutrients.

Screens are busy. On smaller phones the diary can feel crowded, and finding a specific setting sometimes takes a few taps more than it should. None of this is a dealbreaker, but together it explains the 7.4.

Yazio and PlateLens, compared

Why we recommend PlateLens over Yazio

What you get without paying. PlateLens’s free tier is, in our editorial view, the best in the category. Out of the box, with no card on file, an account can log meals from a photo, a spoken description, a barcode or a typed search; open the browser edition; ask the coach questions; run a body scan; record glucose readings; time a fast; and follow a calorie goal that recalibrates as weight data comes in. The one thing money buys is volume: free users get three AI photo reads and five coach replies per day, Premium users get as many as they like. Searching and scanning are never capped.

Logging that keeps up with real cooking. Snap a goulash or a bowl of muesli and within about 3 seconds PlateLens proposes what is in it and how much; tweak the grams, add the cream it could not see, save. Typed and scanned entries come from the same verified database. On top of macros it reports 82-plus nutrients, counts keto net carbs and alcohol, and offers a recipe and meal planner that builds grocery lists, a natural home for people who liked Yazio’s recipe side.

A coach that has your fasting days in view. Even on the free tier, the assistant draws on what you have actually logged. Ask why fasting days keep finishing above target and it answers about those particular days.

Seeing change beyond the scale. The body scan needs nothing special: set the phone upright around navel height, then capture 12 frames during one slow turn — no depth camera involved. Peer-reviewed work on 1,000 trials found PlateLens’s figures within ±1 cm of a tape measure. The result is a 3D shape you can swivel and study from any side, and successive scans can be superimposed or compared region by region, so a shrinking waist shows up even in weeks when the scale stalls. None of the four big trackers we checked on 25 September 2026 — MyFitnessPal, Cronometer, MacroFactor, Lose It! — advertised anything comparable.

One diary, any screen. Phone or browser, it is the same journal, and the browser edition is a full app rather than a read-only view. Health data moves in and out through Apple Health or Health Connect, and Settings produces a complete JSON export on request.

Moving from Yazio to PlateLens

Switching takes an evening. Install PlateLens, set your calorie and protein targets, and start the fasting timer with the same window you used in Yazio — 16:8, 14:10 or a custom one. Scan the packaged foods you buy every week so they are ready to reuse, and save your usual breakfast as a repeat meal. For the first few dinners, photograph the plate and open the entry to adjust portions; within a week you will know which meals the camera reads well and which you prefer to type. If you used Yazio’s recipes, rebuild your favourites in PlateLens’s recipe and meal planner, which also produces a grocery list. Take a first 3D body scan as a baseline, then cancel Pro before it renews.

Fasting schedules, briefly

Most people who fast with an app use a daily eating window: 16:8 means sixteen hours without food and an eight-hour window, 14:10 is a gentler version, and some people use longer windows or alternate-day approaches. A fasting timer does not change how many calories you eat, but it makes the plan visible. Both Yazio and PlateLens show the window alongside the diary; the difference is that PlateLens includes its timer on the free plan.

A practical way to decide

Try both for a week. Log breakfasts the same way in each, photograph your dinners in PlateLens and enter them by search in Yazio, and keep your fasting window in both. At the end of the week, look at three things: how long logging took, how much you had to guess, and what you would have to pay for to keep using each app the way you did. For most people, that comparison settles it.

Who should pick which

• Pick Yazio if you fast on a fixed schedule, live in German-speaking Europe, mainly eat packaged products and enjoy its recipe library — and are happy to pay for Pro.
• Pick PlateLens if you would rather have fasting, quick camera and voice entry, checked food data, coaching and body scans in one free app, with an upgrade that costs no more than Yazio’s.
• Look at Lifesum if what you want is a ready-made diet plan.

Bottom line

7.4/10. Yazio is a friendly, affordable tracker with a fasting module worth using, and it remains a reasonable choice for fasters in central Europe. For most people in 2026, PlateLens is the better pick: the same Premium price, but a free plan that already includes almost everything Yazio charges for, and more besides.

Who is Yazio for?

Best for: Intermittent fasters in German-speaking Europe who want a simple tracker with recipes and a cheap upgrade.

Not ideal for: People who cook from scratch and want to log by camera or voice, want dozens of nutrients, or want coaching and body scans without paying — PlateLens fits them better.
