About
AllerLens helps you review ingredient labels faster when shopping, cooking, or checking snacks for your family.
Set your allergy watchlist once, then scan a label with the camera, choose a photo, or paste ingredients. AllerLens highlights matching ingredients directly in the label text, separates red ingredient warnings from yellow advisory language, and keeps your recent checks on your device.
Features:
- Big 9 allergen watchlist: milk, egg, fish, shellfish, tree nuts, peanuts, wheat, soy, and sesame.
- Custom watch words for personal or family-specific allergies.
- Camera and photo label scanning with on-device text recognition.
- Red warnings for matched ingredients.
- Yellow caution for advisory language such as may contain or shared equipment notes.
- Blue highlights for negated claims such as peanut-free.
- Local scan history and scan missions.
- No account required.
AllerLens is a label-review helper, not a medical guarantee. OCR and ingredient rules can miss or misread text. AllerLens does not guarantee accuracy or food safety and does not claim a food is safe. Always read the full package label yourself and follow advice from your clinician or allergist.
