Any Palm OS hardware
Palm OS 3.0

A handy-dandy Palm OS device application for calculating tips on anything, but especially useful after you, or perhaps a group of people, have consumed vast quantities of food and the ol' brain isn't working to its full capacity.

Version 5.0 with an improved User interface: There is a drop-down list for the amount and one for the group. You can enter either of these values using the appropriate drop-down list or graffiti. There is a tax field where you can enter the local tax rate or leave it set at zero.

There is also a way to enter your own tip rate which is described in the accompanying readme file. QuickTip also supports the Palm OS number format.
