Yazio has a free version, but most recipes, diet plans and advanced features are behind Premium. Suu's free tier includes core calorie + macro + water tracking, 3 AI analyses per day (voice/text), and Apple Health / Health Connect sync; Premium has a 3-day free trial.

Is there an app that does fasting and water tracking together?

Yazio is strong at intermittent fasting but its water tracking is basic. Suu tracks beverage hydration scientifically and adds calories, macros and exercise. Many people use them side by side — Yazio for the fasting timer, Suu for hydration + all-in-one nutrition.

Suu vs Yazio: Which Is Better? (2026 Comparison)

It depends on your needs. If you want water + calories + exercise in one app, by voice or photo and with real hydration tracking, Suu is better: voice meal logging, 91-beverage dehydration science and Arabic RTL aren't in Yazio.
