Do you plan on making an Android app that uses GPS? I don't use foursquare, nor do I intend on using it just for the functionality of DontEat.at. I'd prefer to just open up my DontEat.at app and it immediately informing me about the health code status of the restaurant I'm at/next to. Due to it not being limited to the limit of a text message, much more could also be explained in the analysis.

Also, if you do make an app, it shouldn't require a foursquare account to use it.
