Yazio vs Lifesum 2026: Which Diet App Is Better?
Yazio vs Lifesum, which is better?
Both are structured diet apps with meal planning and recipe libraries, making this a closer comparison than most. Yazio has stronger intermittent fasting tracking and a slightly larger food database. Lifesum has a more visually polished interface and a broader range of diet plan styles. Neither app offers AI photo logging or a conversational nutrition coach. If those features matter to you more than meal planning structure, Welling logs meals in 2.6 seconds on average and includes a real-time AI nutrition coach that neither Yazio nor Lifesum has.

What Is Yazio Built For?
Yazio is a calorie counter and diet tracker built around meal planning. You can plan meals in advance, choose from diet modes including low carb, keto, and balanced eating, and the app includes a dedicated intermittent fasting tracker with timers and fasting window guidance. The food database covers a wide range of packaged products and common dishes, with barcode scanning for quick logging of packaged items.
Yazio's strength is in combining planning ahead with flexible diet mode selection, which suits people who like to organise their eating in advance and want the app to adapt to a specific dietary style they are following.
What Is Lifesum Built For?
Lifesum takes a similar overall approach to Yazio: structured diet plans, a recipe library, and goal-based meal suggestions. The visual presentation leans more heavily into colourful graphics and progress tracking, which gives it a slightly different feel even though the underlying functionality, plan-based eating with a food diary, is conceptually similar to Yazio's.
Lifesum offers diet modes covering keto, balanced eating, and other popular approaches, with recipes designed to fit each one. The food database is comparable in scope to Yazio's, focused on supporting its own plan and recipe ecosystem more than maximising general search coverage.
Which App Has Better Meal Planning?
Both apps offer meal planning features, and the comparison here comes down to depth and flexibility rather than one app clearly outperforming the other.
Yazio's meal planning allows you to plan meals for the week ahead and log directly from those plans, reducing daily decision-making. The planning interface is functional and integrates cleanly with its diet mode selection.
Lifesum's meal planning is similarly structured but leans more on its recipe library and suggested meal ideas tailored to your chosen goal. The visual presentation of recipes and progress is generally considered more polished and engaging than Yazio's more utilitarian approach.
For users who prioritise visual appeal and recipe inspiration, Lifesum has a slight edge. For users who want straightforward weekly meal planning with less visual flourish, Yazio's approach is equally functional.
Which App Has a Better Food Database?
Yazio's database is generally considered slightly larger and more comprehensive for general food search outside of its own recipe content, with solid coverage of European and US packaged products given its origins.
Lifesum's database is tightly integrated with its recipe library, meaning logging from Lifesum's own recipes is fast and accurate, but general food search outside that ecosystem has somewhat less coverage compared to Yazio.
Neither database approaches the scale of MyFitnessPal, and both have more limited coverage of home-cooked and international dishes, particularly Asian cuisines, compared to AI-driven apps that identify food directly from a photo rather than relying on database matching.
Intermittent Fasting: Yazio vs Lifesum
This is one of the clearer differentiators between the two apps. Yazio has a more developed intermittent fasting feature set, with dedicated fasting timers, customisable fasting windows, and tracking that integrates fasting periods with your calorie and macro goals.
Lifesum supports intermittent fasting as one of its diet plan options but with less dedicated tooling around it compared to Yazio's more fully built-out fasting tracker.
For users specifically interested in combining calorie tracking with intermittent fasting, Yazio is the stronger choice between these two apps on this particular feature.
Which App Is Easier to Use Daily?
Lifesum's interface is generally regarded as more visually engaging, with colourful progress rings and a polished recipe browsing experience that makes daily use feel less clinical.
Yazio's interface is more straightforward and utilitarian, which some users prefer for reducing visual clutter and getting to the core logging task more directly.
Neither app offers AI photo, chat, or voice logging, so daily logging speed for both depends on database search and barcode scanning, similar in practice across both apps.
How Do Yazio and Lifesum Compare on Price?
Yazio free includes core calorie counting, barcode scanning, and basic diet modes. Yazio PRO unlocks meal planning, advanced fasting tracking, and additional nutrient data.
Lifesum free includes a basic food diary with limited diet plan access. Lifesum Premium unlocks the full diet plan library, advanced recipes, and detailed nutrient tracking.
Pricing between the two is broadly comparable, with both gating their most distinctive features, fasting tools for Yazio, full recipe and plan access for Lifesum, behind a premium subscription.
Which App Should You Choose?
Choose Yazio if: intermittent fasting tracking is a priority, you want slightly broader general food database coverage, and you prefer a more utilitarian interface over a heavily visual one.
Choose Lifesum if: visual design and recipe browsing motivate you more, you want a polished, guided experience for following a specific diet plan, and intermittent fasting is not a core requirement.
Is There a Better Alternative to Both?
Yazio and Lifesum are both solid, broadly similar diet planning apps. Neither has moved beyond the search-and-log model of food tracking, and neither offers AI photo recognition or a conversational coaching layer that responds to your actual logged data in real time.
Welling logs meals in 2.6 seconds on average through photo, chat, or voice, with 95.6 percent food identification accuracy across 15,000 tested meals and a portion estimation error of 1.2 percent. Rather than requiring you to plan meals in advance to get guidance, Welling's AI nutrition coach responds to your actual day as it happens, answering questions like what to eat next based on your remaining targets. It is built for global and international foods, not only Western meals, which addresses a coverage gap present in both Yazio and Lifesum's databases.
For someone choosing between these two similar apps mainly because neither felt like a significant upgrade, Welling represents a genuinely different approach worth comparing against both.
