I used version 1 for basic calculations and liked it. But version 2 is a huge improvement with features for every conceivable needs. You pretty much have to go through the help file to learn about everything it does because the interface is quite plain. But it hides a lot of functionality. Nice work, thank you.

A nice, compact tool that does everything I could think of as far ac calculations and conversions. Simple syntax, you just enter something like "80 F -> C" to convert farenheit to celsius, for example. But it does much, much more than just that! Full-fledged formulas, tons of functions, numeric bases, complex numbers. It's a dream machine. :)
