Application description

1-Calc is a revolutionary calculator for the Treo 850w. It uses big buttons you can easily hit with your finger. The buttons provide clear audible & visual feedback of being pressed. It has been designed to be your "everyday" calculator that you can quickly pick up & use for a few basic calculations. But 1-Calc is much more than this. It has more features than would be found on a $150 graphing calculator in the stores. The 2 lines of buttons can be scrolled to display other functions including:
