The Best Calorie Counting App in 2026: Suu vs MyFitnessPal, Yazio, Lifesum and Cronometer

The best calorie counting apps in 2026

Ranked by who each one is actually for. Every app here counts calories and macros correctly; the differences are in how fast you can log, how much the free tier gives you, and what else the app knows about your day.

1. Suu — best if logging is what you keep skipping

   Free on iOS and Android. Photograph the meal or say it out loud and the AI extracts calories, protein, carbs and fat; it separates solids from liquids automatically, so a coffee logged by voice lands in both the calorie total and the hydration total. Also tracks 91 beverages with its own hydration factor and records GPS workouts across ~50 activities, and the three feed each other — a logged run raises the water goal, a salty meal adds digestion water. Free tier includes three AI analyses a day. Honest limits: the branded-food database is smaller than MyFitnessPal's and there is no recipe library.

2. MyFitnessPal — best food database, still

   The largest food and restaurant database in the category by a wide margin, built from millions of user-contributed entries, plus the broadest barcode coverage. If you eat out often or buy a lot of branded products, nothing else finds your item as reliably. The costs: barcode scanning moved behind Premium, the free tier carries ads, and non-English entries are community-sourced and often unverified. Water tracking is a plain counter.

3. Cronometer — best for micronutrient precision

   The serious choice for anyone tracking vitamins and minerals rather than just calories — verified data sources rather than crowd-sourced entries, and 80+ micronutrients at gram level. Favoured by people doing clinical or protocol-driven tracking. The interface is dense, there is no voice or photo logging, and localization is mostly English. Overkill if you only want a calorie number.

4. MacroFactor — best adaptive calorie target

   Rather than fixing a target from a formula at signup, it estimates your actual energy expenditure from your weight trend and logged intake, then adjusts the target every week. That is the correct answer to the most common complaint about calorie counting — that the number stops working after a few weeks. Subscription only, with no meaningful free tier, and no water or hydration tracking.

5. Yazio — best for recipes and fasting

   German-made and strong across Europe, with a genuinely good intermittent-fasting tracker, a large recipe library and diet plans. Sleek interface and solid localization in several European languages. Voice and photo logging are limited, water tracking is basic, and most of the recipe and plan content sits behind Premium.

6. Lifesum — best-looking, plan-driven

   Swedish-made and the most visually appealing app here, built around lifestyle plans — keto, high-protein, intermittent fasting — with a food rating system that grades what you log. Most of the experience requires Premium, localization outside major European languages is limited, and macro/micro depth does not approach Cronometer's.

Full feature comparison

The real question is what makes you stop logging

Every app on this list will give you an accurate calorie number if you enter your food accurately. The failure is never arithmetic — it is friction. People quit because a Tuesday dinner takes four minutes to enter, or because the thing they ate is not in the database, or because the target stopped feeling right two weeks in and nothing recalculated it.

Pick against your own failure mode rather than against a feature list:

• "The food I eat is never in there." → MyFitnessPal. Its database advantage over everything else here is real and unlikely to be closed.
• "Entering meals takes too long." → Suu. A photograph or a spoken sentence is the fastest input in this group, and the free tier includes three AI analyses a day.
• "My target stopped working after a month." → MacroFactor. It infers your real expenditure from your weight trend instead of trusting a signup formula.
• "I need to know my iron and B12, not just calories." → Cronometer. Nothing else here is close.
• "I need something to cook and a fasting window." → Yazio, or Lifesum if the plans matter more than the recipes.

Three more worth knowing about

These did not make the main table but come up constantly and are the right answer for some people:

• Lose It! — a long-standing, straightforward calorie counter with a good barcode scanner and a friendlier free tier than MyFitnessPal's. A reasonable pick if you want MyFitnessPal's approach with fewer paywalls.
• Noom — not really a calorie counter but a behaviour-change programme with logging attached, priced accordingly. Worth it if you want coaching and psychology; expensive if all you wanted was a tracker.
• Cal AI — photo-first calorie estimation, in the same category as Suu's photo analysis but without water or exercise tracking around it. We compare the two directly in Suu vs Cal AI.

How accurate is photo-based calorie counting, honestly

Photo estimation is good at identifying what a food is and poor at knowing how much of it there is. Depth and density are the hard part: the model can tell chicken from salmon reliably, but it cannot see the oil the chicken was cooked in or weigh the rice underneath it.

In practice this means photo logging is accurate enough to keep a weekly average honest and not accurate enough to hit a 50-calorie daily target. The right use is speed — logging something approximate in five seconds beats logging nothing at all, which is the actual alternative on a busy day. When precision matters for a specific meal, weigh it and enter it manually.

We go into this in more detail, including where the errors cluster, in how accurate AI calorie counting really is.
