Features

Built for everyday nutrition

Six features that quietly turn good days into great habits.

AI

AI Food Scanner

Snap any meal and get instant nutrition. No more guessing servings or hunting menus.

Nutri-Score

A–E Health Score

Every food gets a clear letter grade based on the same principles as Europe's Nutri-Score — at a glance, you know what's nourishing and what isn't.

Mifflin–St Jeor

Personalized calorie goal

Daily targets calculated from the Mifflin-St Jeor BMR equation, your activity, your goal, and your chosen pace.

Evidence-based

Balanced macros

Protein, carbs and fat targets calibrated to keep you satisfied — protein for satiety, carbs for fuel, fat for hormones.

Habit science

Streaks & achievements

Habit-building backed by gamification research: daily streaks, badges, and gentle nudges that compound into real change.

Inclusive

108 languages

From English to Swahili to Hawaiian. Full right-to-left support for Arabic, Hebrew, Persian, Urdu and more.

How it works

Three taps to better days

The Science

Every feature is backed by peer-reviewed research

We don't invent. We translate decades of nutrition science into one calm app — and we cite our sources.

Privacy by design

Your diary lives on your device

We can't see what you eat. Your logs, weight history and goals are stored locally — there's no account, no cloud sync, no tracking. SkinnyScan works fully offline.

FAQ
