iPhone
Scan a barcode, show your allergy card in 24 languages, keep an eye on official recalls – your shield for food allergies, out and about and in the shops.
Your food allergy shield — on the go, while you shop, and in the background.
TrustBite is with you through everyday life with food allergies: show your allergy card in 24 languages, scan products for a traffic-light verdict, and let the Recall Radar filter official alerts from 15 European sources down to your allergens.
ON THE GO — YOUR CARD SPEAKS 24 LANGUAGES
Create a personal card with all your allergies and show it to restaurant staff in Italy, Japan or Thailand — in their language. They understand instantly. The card others charge around $19 per language for: included here in 24 languages, available offline. Plus the AI menu scan (checked dish by dish) and the live translator for the "is this safe for me?" conversation.
WHILE YOU SHOP — A TRAFFIC LIGHT INSTEAD OF FINE PRINT
Scan barcodes free and unlimited: an instant traffic light (green / yellow / red) based on your profile, powered by Open Food Facts. No barcode? A photo is enough — AI analyses the ingredient list. Save safe products to your Safe Shelf. And in Free-from finds, others show what they just spotted on the shelf — with photo, shop and country. A community tip, not a verdict: check the label anyway.
IN THE BACKGROUND — YOUR SHIELD KEEPS WORKING
Recall Radar: official food alerts from 14 European countries + the EU rapid alert system (incl. FSA, lebensmittelwarnung.de, RappelConso, AESAN), automatically filtered to your allergens — with a timestamp of the last check. Recipe Watchdog: checks your saved products weekly for ingredient changes and reminds you to re-read the label. Auto-injector reminder: know in time, before your pen expires. PRO: one bundled weekly push for recipe changes and new recall alerts.
No alert system is complete — keep checking labels yourself. TrustBite never gives the all-clear.
PRIVACY-FIRST
Your allergy data stays on your device + your private Firebase account. No tracking, no selling of data.

NOTE
TrustBite is an aid, not a medical device. Always verify with staff or check ingredients yourself when severe allergies are involved. The app does not replace medical advice. In case of severe or life-threatening reactions, call emergency services or see a doctor immediately.
We built TrustBite because we live with food allergies ourselves. We hope your next grocery run, your next dinner — and your next trip — become a little safer and a lot more relaxed.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
New: scan barcodes straight from your home screen – just press and hold the app icon. New: we ask you once how you found TrustBite. Tidier settings: “Rate app” and “Invite friends” are easier to find. Fixed: you can clear the expiry date of your emergency medication again. The recall radar now shows very recent alerts as “just now”.
