DISCLAIMER
TrustBite is an aid, not a medical device. Always verify with restaurant staff or check ingredients yourself when severe allergy is at stake. The app cannot replace professional medical advice. In case of a severe or life-threatening reaction, call emergency services immediately or seek a doctor.
We built TrustBite because we travel with allergies ourselves. We hope it makes your next trip — or just your next dinner — a bit safer and a lot less stressful.
