Allergen safety cards in 24 languages, barcode scanner, and AI photo analysis — built for travelers with food allergies.
How it works
Set up once, use everywhere. No WiFi needed for the card.
Select up to 14 allergens and set your severity level. TrustBite remembers your profile — even offline.
Tap a language flag and hand your phone to the waiter. Your allergens appear in their language, instantly.
Scan product barcodes or photograph a menu. AI flags anything that's unsafe for you in seconds.
Features
One app for cards, scanning, and AI analysis — always in your pocket.
Arabic, Thai, Japanese, Chinese, German and 19 more. Show any waiter exactly what you can't eat — in their language.
Point at any barcode. Instant traffic-light result — green, yellow, or red — against your personal allergen profile.
Photograph the ingredient label on the back of any packaged food. Google Gemini reads it and flags every allergen that's unsafe for you — instantly.
Share your allergen card as an image via WhatsApp, email, or AirDrop — before you arrive at a restaurant, or when friends are cooking for you so they know exactly what to avoid.
