calCOOLator is a simple calculator application for Google's Android mobile phone platform.
Back in the mid 1990's, there was a nice calculator program called 'calCOOLator!' for the then-new PalmOS. The idea is that you have two text fields for numeric expressions. You work in one, and get a running total in the other. You can switch at any time, using the total in a new expression.
I haven't seen another calculator application like this for any mobile platform since the original calCOOLator! stopped working on modern PalmOS devices, so.... I wrote my own.
This application is now available on the Android Market!
You can also check out the changelog.
And how about a screenshot?

Sometimes people just aren't happy. Here's some fun feedback I've got:
