About this app

Metriva is a calorie counter, macro tracker, and habit journal built around one core idea: your health data belongs to you. No account creation, no sign-ups, and no cloud synchronization. Everything you log lives securely inside a private local database on your phone.

Whether you want to track your weight, monitor muscle-building macros, or maintain a healthy lifestyle, Metriva gives you premium fitness and nutrition tracking tools with absolute data privacy.
