Of all the Android programs available for calculating tips and splitting bills, this one is the silliest. I also think it's the most practical, functional, and fun to use. It definitely has the best name: TippoBilloSplitamus. Say that five times fast. It's not difficult, but it's fun! This program will be in the *new* Android Market as well as the Apple App Store very soon. The cost is $2.00.
