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.
