DozStopwatch

The Dozenal Suite is a set of six apps of dozenal utilities. They run on Apple’s mobiles (with iOS 18 or higher). On any timing device, the day is divided by successive powers of 12, providing metric time reckoning based on twelves rather than tens. The leftmost digit changes every 2 hours (1/12 day), the next digit every 10 minutes, the next every 50 seconds. If displayed, the fourth digit changes every 4 1/6 seconds, the fifth digit every 25/72 second, and the 6th digits every 25/864 second. That's much simpler and easier than the current time reckoning, which uses a mixture of bases 10, 12, 2, and 60. In the dozenal number base, because the number 10 is one dozen, numerals ten and eleven must be single digits. They are represented by the symbols invented long ago by Isaac Pitman: rotated 2 for ten, and rotated 3 for eleven. Those are used by the two major dozenal societies, the Dozenal Society of America and the Dozenal Society of Great Britain. In plain text with dozenal numbers, ten is designated by the letter A, and eleven by the letter B. The stopwatch advances by the last digit, the Primel metrology's twinkling (5th digit) or vibe (6th digit). Time elapsed may be shown for up to dozenal 60 (decimal 72) successive laps independently.
