Cronometer vs Lifesum: Which Calorie App Should You Pick in 2026?
Published: · Furkan Mert Fındıklı · 7 min read
Short answer: Cronometer is the better pick if accuracy and vitamins and minerals matter: its database is built on carefully verified sources, it tracks 80+ micronutrients and its free tier is generous. Lifesum wins if you want a polished, guided experience with diet plans and recipes. Neither models hydration properly, and the workouts you log don't change your water goal.
Cronometer and Lifesum both count calories and macros, but they are built for very different people. Cronometer is for people who care about the accuracy of the numbers and the detail of vitamins and minerals; Lifesum is for people who want calorie tracking to feel like a pleasant, guided habit.
The right choice depends on which problem you are actually solving — knowing exactly what you ate, or getting help to start eating better.

Choose Cronometer if accuracy and micronutrients matter
Cronometer's strength is the source behind the numbers. Its database is built on lab-analysed, carefully verified sources, so you run into fewer conflicting user entries for the same food.
Where it really pulls ahead is micronutrients: it tracks more than 80 vitamins and minerals. If you need to keep an eye on a specific nutrient — iron, B12 or vitamin D — no app in this category does it better. Its free tier is also generous enough to log seriously for a long time.
The trade-off is the interface: Cronometer is dense and data-first. Photo meal logging sits in the paid Gold plan, and recipes and diet plans are thin.
Choose Lifesum if you want a guided, pleasant start
Lifesum's strength is the experience around the numbers. Onboarding is gentle, the interface is uncluttered, and the Life Score idea — rating the quality of what you ate, not just the quantity — gives beginners feedback a bare calorie count does not.
Its recipes and structured diet plans also answer the “what should I eat?” question. The most common failure in calorie tracking is not inaccuracy, it's quitting in week two — an app that makes the first fortnight feel encouraging has a real advantage.
The trade-off is the free tier: several of Lifesum's distinctive features sit behind Premium, and you notice it sooner than in Cronometer.
Quick rule of thumb: if your problem is knowing exactly what you ate, Cronometer. If your problem is starting to eat better and sticking with it, Lifesum. If your problem is that food is only one part of the picture, keep reading.
What both of them leave on the table
Cronometer and Lifesum are nutrition apps that added a water counter and a light exercise log, rather than apps designed around all three from the start. In practice two things go untracked in any meaningful way.
Hydration is a tally, not a model. Both count glasses without distinguishing what you drank — 250 ml of coffee and 250 ml of water are not the same for fluid balance, yet both apps count them the same. Neither adjusts your target for a hot day.
Exercise does not feed anything. You can log a workout and your calorie allowance may rise, but the fluid you lost through sweat is not accounted for anywhere.
Disclosure: where our own app fits
We publish this comparison and we also make a competing app, so treat this section as advertising and skip it if you prefer — the Cronometer and Lifesum verdict above stands on its own.
Suu was built around the gap described above: water, calories and exercise as one connected system rather than three parallel logs. A run you record with GPS raises the daily water goal from estimated sweat loss; each of 91 beverages counts with its real hydration value; you log meals by voice or text (3 AI analyses a day on the free plan), with photo analysis on Premium.
Where Suu is behind: it comes nowhere near Cronometer on vitamin and mineral detail or Lifesum on recipes and diet plans, and its food database is smaller than either. If those are your priority, the two apps above remain the better choice and we would rather say so.
Verdict
Cronometer — verified database, 80+ micronutrients, generous free tier. Best for anyone tracking a specific nutrient or overall diet quality in detail.
Lifesum — polished interface, Life Score, recipes and diet plans. Best for first-time trackers who want guidance.
Neither — if you want hydration modelled properly and your workouts to change your daily targets, both fall short by design, and that is the gap Suu is built for.
If you are choosing purely between these two: try Cronometer's free tier first, since it gets you further before asking for money.
