## What is DozTimer?

The Dozenal Suite is a set of five apps for dozenalists! They run on Apple’s mobiles (with iOS 18 or later).

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 and the fifth digit every 25/72 second.

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 the plain text below, ten is designated by the letter A, and eleven by the letter B.

The timer app may be set for any time between dozenal 000.01 and BBB.BB. It counts down by the last digit, the Primel metrology's twinkling.
