New v2.3 (free update) - supports landscape, square screen and VGA Pocket PCs.

1-Calc is a revolutionary calculator for the Pocket PC. 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. Using the up/down buttons on your Pocket PC or the green option button, you can quickly scroll the top 2 lines of buttons to display other functions including:

Basic Functions

Backspace to edit mistakes, brackets to frame your expressions correctly.

Also supports Algebraic, RPN & DAL calculator modes.

Unit Converter
A full unit converter that not only helps for the everyday conversions (e.g. km/miles, Fahrenheit/Celsius), but also for the unexpected (what's my shoe size in Europe?!?). Unit conversions include:

Tip Calculator
Finally work out who should pay when you're out with friends!

Base converter
Quickly convert between binary, decimal, hexadecimal & octal.

Customization
Want to display all your buttons at the same time? No problem! 1-Calc can display 40 smaller buttons on 1 page, and a quick tap of the up/down button can display 80 more.

1-Calc also allows button groups to be customized so you can display just the buttons important to your everyday calculations.

Plus, 1-Calc has many different options to allow you to set up 1-Calc for how you want it:

• Normal, fixed, scientific, engineering notation
• Display using regional settings
• Repeated equals
• Cleartype support

Skinning
Skinning (changing how the calculator looks) is an integral feature of 1-Calc. See the Omega One web site for details instructions on how to skin 1-Calc to make it look unique!
