RPN HexCalc Lite app for iPhone and iPad

This lite version of RPN HexCalc does not support any decimal functions, but instead provides useful hexadecimal functions, including:

Bit Set,
Bit Clear,
Bit Shift Left,
Bit Shift Right,
Reverse Bit Order,
Invert Bits,
Divide (with fractional results),
and of course Multiply, Subtract and Add.

(Please get the full version of RPN HexCalc in order to get additional decimal functions including: hex-to-dec and dec-to-hex conversions, decimal-based calculations, power functions, logarithmic functions, and trigonometric functions.)

Bit Set, Bit Clear, Bit Shift Left, and Bit Shift Right are all implemented by typing a decimal number and then tapping BIT, then SET, CLR, SHL, or SHR.

There are 6 storage registers (A through F) supported by this calculator.

A backspace key has been provided for convenience. Also this calculator supports both portrait and landscape orientations.

The goal of this calculator is to provide desirable hexadecimal functions that are not usually found on other scientific calculators. At the same time, the calculator is intended to have an uncluttered interface with the largest possible keys, while still minimizing the number of keystrokes required to implement a function.
