Tippy

Tippy is a small tip calculator and bill splitter for Windows Mobile. The screenshots speak for themselves: it’s small, it’s fast and it gets the job done. It is incredibly easy to use without a stylus and requires no use of the keyboard. It works well on all resolutions including square screens.
