Great if you dont like the iPhone calculator....
I cant stand the iPhone calculator because the buttons are small, the clear button doesnt work the way I want it to, you cant see what number was inputted last, and it has a tendency to change to landscape mode even though I havent moved the phone. Big Button calculator is a very simple application, but that is all I wanted. The buttons are large and it keeps a running tally of the numbers inputted at the top of the screen, which decreases errors. The clear button clears the last number you inputted but keeps the rest of the numbers, so you dont have to start over. The only suggestion I have is more skins, but Im sure those are on the way!
