You can also download free trial version.

Minimal requirements: Pocket PC 2000 or later

Desktop version exists (look for SciCalc Pocket + Desktop).

You can view numbers in different ways. As fraction, degrees-minutes-seconds, even as Roman Numeral. You can also lower high display precision using ENG, SCI, and FIX modes.With over 550 units grouped in categories, you can survive in metric/U.S./imperial chaos.
Most of the conversion factors are exact, or have 15 digits of accuracy.
Converter can even calculate using natural fractions.
Financial and Date/Time mode lets you easily perform financial calculations.
You can calculate time difference between dates and view result in different units.
In Integer mode you can perform any logical operation. You can switch between different number bases and byte widths. You can also change signed/unsigned attribute of the number.
Due to unique calculator design, you can easily convert, add or subtract Percents, Decibels and Nepers. You can use such unit numbers in memory, in constant calculations and even in parentheses !Example:10 + 10 %  = 11.10 + 10 dB10 = 100.10 + 10 dB20 = 31.622766601683810 + 10 Np = 220264.657948067It has never been so easy !
