I've just released an updated version of Tiproid, a tip calculator, for Android 1.5.

I just needed to change of the keypad entry layout to make it work with cupcake. I also made the keys bigger as requested by a few people.

Tiproid is on the Android Market, just search for it. Alternatively you can also download it from my Android apps page.

As usual the source code is available from my public subversion repository.
