My girlfriend is turning 30 and there will be a party in February or March. She asked me if it would be possible to create an iOS app that the guests can download and use for ordering from the bar, and for sending music related messages to the DJ. Technically it's a very simple app. (I'm not a professional developer, but I've done some apps on my spare time.) But my concern is that Apple will deny this app, due to its relatively small target group (50-100 people). What do you think?
