I made an App to help find out food intolerances. Basically make it super easy to enter what you have eaten. Not even based on individual items, just basic foods like soy, tomatoes, onions... help me figure out that it was garlic which was causing all the trouble.

Currently trying to release it on IOS, but Apple is very strict with these types of apps.
