• Support diets and preferences such as vegan, vegetarian, keto, and gluten-free
• Add custom restrictions in your own words
• Get a clear verdict: Safe, Caution, Avoid, or Unknown
• Keep a local scan history on your device

The app is designed to be simple, careful, and easy to use in everyday shopping.

❓ Frequently Asked Questions

How does Leaf work?

Leaf uses public food databases and AI analysis to read product ingredients, then checks them against your personal restriction profile.

You get a verdict based on the available product data and the restrictions you set in the app.

Is the analysis always 100% accurate?
