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.

Stopwatch

A stopwatch that records every lap and split to 1/100 of a second — and keeps the whole run after you stop. Most stopwatches throw the run away the moment you reset. This one anchors timing to the system wall clock so it never drifts, flags your fastest and slowest lap the instant you record them, saves the run to History, and scores how even your pacing was on a 0-100 consistency scale. Laps, splits, charts and totals — not just a number that disappears. WHAT YOU GET - Lap time and split time read to the hundredth, newest lap always on top - Your fastest and slowest lap flagged automatically while you are still timing - A 0-100 consistency score that tells you whether your pace held or drifted - Saved runs with lap charts, pace-variation graphs and best / average / worst breakdowns - Two saved runs placed side by side, lap by lap, with the gap shown on every row - Lifetime totals: runs timed, laps recorded, time tracked, best lap ever PERFECT FOR - Runners timing track laps, tempo runs and interval reps - Lifters and HIIT athletes marking rounds and keeping rest honest - Coaches timing repeats and comparing one athlete's runs week to week - Anyone timing brews, bakes, lab reactions or focused study blocks WHY NOT JUST USE THE BUILT-IN CLOCK APP? Because it forgets. The stock stopwatch shows a lap list that vanishes the second you reset — no saved runs, no chart, no side-by-side comparison, no export. Here every run is kept, labelled with a preset (Sports, Cooking, Study), grouped by day, and ready to reopen months later. Tap Lap and the clock keeps running; the screen stays lit so you never lose your read mid-run. PRIVACY Every run is stored on your device only. No account, no sign-in, no ads, no third-party tracking. Works fully offline, in airplane mode, anywhere. FULL ACCESS Full access unlocks unlimited saved runs, per-run lap charts, the best / average / worst breakdown, run-vs-run comparison, and CSV export of any session you have timed. Choose a weekly plan, a yearly plan, or a one-time lifetime unlock — the lifetime option is a single payment with nothing to renew. Tap Start, tap Lap at every checkpoint, then save the run and watch your consistency score climb.
