YAZIO vs Lifesum (2027)
By Theo Marchetti · Published October 22, 2026 · Updated October 22, 2026
YAZIO and Lifesum are the two best-known calorie counters to come out of Europe. YAZIO pairs counting with intermittent fasting and a recipe library; Lifesum builds the app around ready-made diet plans.
The short answer
Both apps are friendly, well-designed calorie counters with strong coverage of European supermarket products. Choose YAZIO if you want calorie counting and intermittent fasting in one place. Choose Lifesum if you want the app to give you a way of eating, not just a number.

Where each one wins
YAZIO suits people who already fast or want to try a time-restricted eating pattern, because the eating window and the food log sit together. Its recipe library makes home cooking quick to log.
Lifesum suits people who find an open calorie budget hard to fill. Choosing a plan changes the app’s targets and suggestions, which gives the first weeks a structure.
What to watch with both
Most of the plans, recipes and deeper analysis in both apps are part of the paid tier, so try the free version first and check what you would actually use. As with any packaged diet plan, very restrictive approaches are harder to sustain, and anyone with a medical condition should talk to a clinician before changing diet.
Other options
If you are in the US and eat at chains often, the US-born trackers usually have wider restaurant coverage. For an overview of every option, see our 2027 ranking.
