About

BinaryClockWatch

Features
Read full description

BinaryClockWatch doesn't show the time like every other watch. It shows it in 13 different number systems, right on your watch face as a complication. From binary and BCD (binary-coded decimal) to octal, hexadecimal, Gray code, balanced ternary, Fibonacci, Babylonian base 60, Braille, Mayan numerals, Roman numerals, Cistercian monk numerals and the I Ching: every system shows hours and minutes its own way, with 20 complications for every watch face family. FEATURES • 13 number systems as watch face complications • Concentric rings, BCD dot grids or inline text, depending on the system • Separate hour and minute rings for more flexibility • Corner complications with a curved dot line along the edge of the watch face • Automatic color adaptation to your system theme • Built-in guide with an explanation and a live example for each of the 13 systems • Completely free: no ads, no in-app purchases, no data collected For everyone who would rather read the time than just glance at it, and for everyone who finds number systems fascinating. BinaryClockWatch runs independently on Apple Watch, no iPhone app required.
