Honest comparison
Kata vs Yazio.
Yazio is one of the better calorie trackers in Europe and considerably cheaper than the American ones. It is still a tracker: it counts, and leaves the deciding to you.
The verdictA sensible European tracker at a sensible price. And the conversation it does not have.
First, fairly
Yazio at a glance.
What it is for
A German calorie, macro and intermittent fasting tracker used in more than 150 markets and 20 languages.
What it costs
There is a genuinely usable free tier. Paid plans are 3 month or 12 month only, with no monthly option, and store prices vary widely by region and cohort: annual plans have been observed anywhere from around 24 to 84 in USD or EUR.
Where it is strongest
Intermittent fasting done properly: several protocols built in, with a timer that behaves like a core feature.
Who it suits
People who fast, cook from recipes, and want a real free tier at a European price.

Honestly
When Yazio is the better choice.
If intermittent fasting is your method, Yazio fits better: several protocols built in, with the timer as a first class feature. The recipe library is good, the free tier real, and the annual price far below the American alternatives.
In short
What, how and why.
- What

- How
- You talk, it logs, then it answers with your protein, your trend and tonight's plan.
- Why
- Numbers are easy to collect. Knowing what to do on a Tuesday is the hard part.

Questions
Asked and answered.
Does Yazio have an AI coach?
It has an AI food scanner and good statistics and insight cards, but no conversational coach you can ask questions of. Saying what is on your mind and getting an answer built from your own data is a different kind of product.
Can Kata do intermittent fasting?
There is no dedicated fasting tracker in Kata today, so if fasting protocols are central to how you eat, Yazio does that better and we would rather say so. Kata handles the eating window in conversation, not as a timer.
