Traveling with food allergies shouldn't be scary.
Mayday turns your phone into a lifesaver at restaurants abroad. Select your allergies, choose the local language, and show a clear, translated allergy card to the waiter — no internet needed, no awkward gestures, no risk of miscommunication.
How it works:
- Pick your allergens from 36 options (nuts, shellfish, gluten, dairy, and more)
- Choose from 38 languages — from Japanese to Arabic, Thai to Finnish
- Tap a card to show it fullscreen, at max brightness, ready for restaurant staff to read
Why Mayday:
- 100% offline — works in airplane mode, in remote villages, anywhere
- Translations written specifically for restaurant staff, not machine-translated menus
- Covers 36 allergens across 6 categories: nuts & seeds, seafood, dairy & eggs, grains, fruits & vegetables, and more
- 38 languages across Europe, Asia, Middle East & Africa
- No account, no signup, no data collected — your allergies stay on your device
- Clean, high-contrast cards designed to be understood at a glance
Whether you're celiac in Tokyo, nut-allergic in Bangkok, or lactose intolerant in Istanbul — Mayday speaks the language your waiter understands.
Built by someone who knows the panic of pointing at a menu and hoping for the best. Travel with confidence.
