Math Duel is an iPad app that lets two students compete against each other for faster time in solving basic facts. The wonderful feature is that each side of the split screen can be set at a different level of difficulty and different operations. (See photo below for settings options) This means that I can have two students use it together, both working at their own level. Great example of an app that supports differentiated instruction. Currently available for $4.99.
