Scan Anything, Know Everything

Lensy transforms your phone camera into an intelligent price scanner. Simply point your camera at any product — from grocery items to electronics — and the AI instantly identifies it, providing the name, estimated price, description, material, brand, and even where to buy it online.

The app supports both single-shot scanning and a powerful Batch Mode, allowing users to rapidly scan multiple items in sequence. All scan results are stored locally with full history management, and can be exported to Excel spreadsheets for professional use.

Built for a Global Audience

With support for 50+ languages and automatic currency detection based on the user's location, Lensy is truly global. The app auto-detects the user's country and adjusts both the display language and currency accordingly.

The freemium model is powered by In-App Purchases through Apple's StoreKit, with a Pro subscription unlocking unlimited scans, batch mode, AI chat follow-ups, auto-save to album, and Excel export capabilities. Authentication is handled securely through Supabase with Apple Sign-In and email OTP verification.
