App Comparisons: Calorie, Exercise and Water Tracking

Updated: August 15, 2026 · · 13 comparisons

Short answer: Three things decide which calorie counter fits you: how fast logging a meal actually is, whether the free tier does real work, and whether exercise updates your daily targets. The comparisons below test all three, app by app.

These pages are written by the Suu team. We name the areas where competing apps are stronger; saying honestly which app suits which user is more useful in the long run.

Most app comparisons count features. We ask one question instead: what does this app do with your data? When you log a meal, does your water target move? When you record a run, does your daily requirement update? Is your coffee counted at its real hydration contribution?

Every comparison states plainly where the competitor is genuinely better — no app is best for everyone. We also say which situations call for Suu and which call for something else.
