This app helps you communicate. It is not medical advice and cannot guarantee a safe meal. Kitchens differ, and cross-contact and shared fryers are common. Always confirm ingredients with staff and carry your prescribed medication. In a medical emergency in Japan, call 119.
Questions
Does the app work without internet?
Yes. Cards, Japanese text, audio and dish pictures are stored on your phone. You only need a connection to start the trial, buy a pass or restore a purchase.
Which allergies and diets are covered?
There are 31 cards, covering gluten and celiac disease, wheat, egg, dairy, peanuts, tree nuts, soy, buckwheat, fish, shellfish, crustaceans and sesame, plus halal, vegan and vegetarian. You can combine several into one declaration.
How do restaurant staff reply?
Staff mode shows your card in large Japanese text and can play it aloud. Staff tap an answer such as safe to eat, can be removed, the broth or sauce contains it, or can't accommodate, and you see the reply.
Is the Japanese audio a real person?
No. The Japanese audio is computer-generated, and you can slow it down.
How much does it cost?
The download is free and includes core phrases and guides. New users can start a one-time 3-day All-Access trial that ends without charging you. After that, choose a 14-Day Trip Pass ($4.99) or Lifetime All-Access ($9.99) on the US App Store. Neither renews.
Can I print or share my card?
Yes. Save a card to Photos, or share, AirDrop or print it from the share sheet. It goes only where you send it.
Why is eating gluten-free in Japan hard?
Regular soy sauce is brewed with wheat, many broths use dashi made from fish, and fryers are often shared. Restaurant menus rarely list allergens, so asking clearly matters.
Which languages is the app available in?
English, French, German, Italian, Spanish, Korean, and Simplified and Traditional Chinese. The cards themselves are in Japanese.
Does the app guarantee my food is safe?
No. It is a communication aid, not medical advice. Always confirm ingredients and shared preparation with staff.
