BaseCalc is a programmer's calculator with a clean and minimalist interface for iOS. It supports direct input and output in bases 2, 10, 16, and special IPv4 format. On top of the classical 4 operations, you can execute common bitwise operations [AND, OR, XOR, NOR, ROTATE, SHIFT, ARITHMETIC SHIFT].

Preference settings allow selecting internal word size (8, 16, 32, or 64 bits), signed/unsigned operations, and representation mode (padding, IPv4, ...).

Starting with version 1.1, Apple Watch support is available with conversions between bases 2, 10, 16, and IPv4 straight from the Apple Watch.
