--------- Gluten-Free Apps ---------
Today, gluten-free applications make it much easier to prepare for a gluten-free trip. Most existing gluten-free apps need data or a wifi connection to work. Normally, these gluten-free applications that work with internet connection, are often very useful for known destinations and/or especially the western world. Gluten-free travel tools that work without an internet connection (e.g. the gluten-free celiac travel card) are often more useful in more exotic countries.
RECOMMENDATION: Always make sure that the listings of gluten-free restaurants found in gluten-free apps that require an internet connection are up to date. If necessary, call the restaurant to confirm that they serve gluten-free food and that they control cross-contamination.
