What I love about apps is how you can take a really simple idea and then create an incredibly useful resource that loads of people will want - Biteappy is a terrific example of this. Available for free download from the iTunes App Store and Google Play, it allows people with food allergies/intolerances and other dietary requirements (to search for restaurants that will suit them.
All you have to do is choose the specific dietary and cuisine criteria, and then the geographical location and the app will identify all the suitable restaurants in the area. Even more cleverly, the app also offers a translation card section with over 25 languages, so when abroad you can communicate dietary preferences to restaurant staff.
Of course, these things are only as good as the restaurants listed on them, but if you come across a gem, you can add it in (it'll then be approved by Biteappy) - over time this will help to make the app totally indispensible.
Biteappy was created by Caroline Oldham, a coeliac with an additional lactose allergy who found it a constant battle to locate suitable restaurants for her dietary needs, even more so when travelling or abroad. She says:
“I have always found it a challenge to eat out especially when abroad and being able to feel confident about it being taken seriously. Whilst a lot of apps allow for a gluten-free search or a vegan search there is nothing that collectively brings all allergies together so Biteappy helps with the many people with multiple allergies.
“My aim for the app is to help others like me who have struggled over the years to start to have the confidence to eat out again.”
