Community
People with allergies photograph free-from products they discover in a shop — and say where they found them.
A photo of the pack, optionally a second one of the ingredients list, plus the product name, the shop, the country, the town if you like, up to 3 of the 14 allergens the pack says it is free from, and a short note.
Others react with a "Thanks" and can comment — so you hear first-hand whether a find is worth the trip to that shop.
The feed shows finds from your own country by default, and you can switch to any other country at any time. Reading needs no account; posting needs a linked account.
Every post goes through AI moderation before it becomes visible. Reporting and blocking are built in.
A find is a personal observation, never a safety verdict. TrustBite never gives the all-clear — always check the label yourself.

Top app — helps me so much! Perfect experience, keep it up. I have the Pro version and I’m completely happy with it.
The app is clear and really easy to use. I love that there’s finally an app for food allergies — and a big plus for people who travel a lot is the huge choice of languages.
A really sensible app — works flawlessly.
Very good app! Thank you!! Works very well … also the barcode scan at my supermarket 😁
Perfect 👌

FAQ
The essentials before you download.
Yes. Once your profile is set up, your allergen card is stored on your device and displays in all 24 languages without any internet connection.
All 14 allergens regulated under EU law: gluten, peanuts, tree nuts, milk, egg, fish, shellfish, soy, sesame, mustard, celery, sulphites, lupin and molluscs.
Yes. TrustBite is free to download and the multilingual allergen card is free to use. Barcode scanning stays free and unlimited; an optional Pro subscription lifts the daily limits on the AI photo and menu analysis.
Yes. TrustBite is a digital allergy card you always carry on your phone and can show to restaurant staff in their own language — 24 languages including Thai, Japanese, Chinese and Arabic.
From 15 official sources: food-safety authorities in 14 European countries plus the EU rapid alert system (RASFF), automatically filtered to the allergens in your profile — with a timestamp of the last check. No alert system is complete, so keep checking labels yourself.
It checks the products you saved once a week for ingredient changes and reminds you to re-read the label when something changed. It reports changes — it never gives the all-clear.
Yes. The safety core of TrustBite — alerts, the barcode traffic light and your card — is always free. An optional Pro subscription adds the weekly push digest and unlimited AI analyses, including the menu scanner.
In the TrustBite community, people with allergies share products they have discovered in a shop: a photo of the pack, the product name, the shop, the country and up to 3 of the 14 allergens the pack says it is free from. Others say thanks and comment; the feed shows your own country by default, and reading needs no account. Every post goes through AI moderation before it becomes visible, and reporting and blocking are built in. A find is another shopper's personal observation — never a safety verdict, so always check the label yourself.
No. TrustBite starts without an account — no email, no password, no sign-in. You can build your profile, show your card, scan barcodes and read the community feed right away. Anonymous users get no cloud record at all; everything stays on the device. An account is optional and only adds cloud backup plus the features that technically need an address: the weekly push digest, posting to the community and the referral programme.
No ads, in any version. There is no advertising ID, no location access and no app-tracking prompt. Usage measurement is off by default — opt-in, not opt-out — and advertising signals stay switched off permanently. Photos the app passes on are stripped of location data twice, once on the device and once on the server. Your data is stored in the EU.
The emergency screen shows your allergies, your severity level and your emergency contact, and the call button dials the number of the country you are in — 112 in Europe, 1669 in Thailand, 119 in Japan, 120 in China. You can also set a reminder to check your adrenaline auto-injector before a trip. All of this is free and works offline.
Download TrustBite free and show your allergen card to any waiter, in any language, in seconds.
