This is my first application for the Palm Pre. It's a simple restaurant tip calculator. I wrote it because there wasn't one, and it seemed an easy way to learn how to write apps for this phone.

By default, it only does whole numbers, because if you insist that your tip be accurate to the penny you are a cheapskate weirdo. Here in the Colonies, we use paper money, not coins. If your bill is $44.22, just enter $45. Don't go all Scrooge McAsperger's on us, ok? But, there is a "scrooge mode" that lets you calculate your tips so that no penny is left behind, if is how you roll.

Tip Calculator is not currently available in Palm's App Catalog, but hopefully it will be some day.

Until then, you can install it via the Preware application for WebOS, which is an installer for many third-party packages. Follow their installation instructions. Basically: first you download and run the WebOS Quick Install Java program; then you use that to install the Preware installer application; then you run Preware on your Pre, and select Tip Calculator from the list of available applications (it is under "Applications/Finance").

Alternately, if you have the WebOS development kit you can just install it from the command line over USB by doing:

palm-install -d usb org.jwz.tipcalculator_1.0.6_all.ipk
