Bit Fiddler

A visual approach to working with base 2 mathematics, BitFiddler is a binary calculator that provides a touch optimized UI for calculating the results of binary operations. Bit-Fiddler's visual approach to manipulating and displaying binary data makes it both a professional tool for the software engineer and a learning resource for CS students.

The free version includes the following features:

- 1, 2, 4, and 8 word modes allows working with values up to 64 bits in length.

- Allows chaining multiple operations together.

- Supports logical and arithmetic shift operations.

- Supports NOT, AND, OR, and XOR operations.

- Provides base-16, base-10, and two’s compliment signed base-10 interpretations of binary values.

- Works in both landscape and portrait modes.

- Saves your calculations automatically when you exit.

Future Features

In the future Bit Fiddler will add the following features as part of updates to the all versions of the app:

- Big-endian mode and little/big endian conversion operations.

- Support for a floating point interpretation like IEEE 754.

- Support for character interpretations like UTF-8, ASCII, and Unicode.

- French and German (when I can find someone to translate strings for me).

- Size settings to make the app more usable for people with poor eyesight.

- Wikipedia integration to provide quick access to articles on binary standards and operations.

- Bug fixes (of course).


A planned "pro" version will add the following features:

- Support for 16 word (128 bit) values

- Circular shift operations.

- Support for fixed float interpretations.

- Saving and loading calculations to files.

- Definition of variables for easy insertion of values (e.g. "MY_BITMASK_HEX_VALUE=0xFFFF").
