How it works
The shape of it
Six marks in, one of three answers out
Arizodo is one loop repeated daily. You mark six things against a standard you wrote; each of the three pillars scores the share of its marks you held; the day is the mean of the three, and falls into one of three bands. Advance is worth a point, stagnation nothing, retreat costs one. Points accumulate onto a ladder of nineteen grades, and that is the entire mechanism — everything below is detail on one of those steps.
The app
See it running
Every screen the app has, running its own stylesheet. Tapping a sector rescores the day by the rule set out above.
How it works
Three pillars, one number
Sleep is a bed time and a wake time, against hours you set. Eat is two marks, clean and fuel: whether the day kept the shape you defined. Move takes walking as the baseline and puts the gym on a weekly quota, settled across the week rather than day by day.
Six marks, checked in a morning phase and an evening phase. The share you hold decides the day.
A day advances at 0.9 or above, holds while it stays above 0.5, and retreats at 0.5 or below. Points never fall below zero, and a grade once reached is kept: retreat spends progress inside the current grade first.
Days close on their own. Any past day can be reopened, and a late edit is marked as an amendment.
A fixed budget of exceptions covers what is external, unforeseeable and not chosen. A fever qualifies; travel belongs in the standard as a clause. Three exceptions with the same cause point to a gap in the standard. When the budget is spent, it is spent.
The ladder
What a year is worth
Rope, then seven colours, then black, then ten dan. The bars show the days each grade takes at a perfect run.

- 8 Dan 八段182
- 9 Dan 九段183
- 10 Dan 十段—
- Year 1 年+365
Nineteen grades carry a name. Past 10 Dan the record counts years instead, struck across the bands where dan never goes — and it has no ceiling.
Black belt at 365 is the anchor. One perfect year, exactly. Every other number on the ladder is derived from it.
The first promotion lands on day nine. The colour grades lengthen geometrically, and brown, at 119 days, is the longest wait below black belt. First dan follows thirty days after black, then roughly one grade every half year. Ten dan is 2,009 points — about five and a half years without a single miss.
Black belt and first dan are kept separate, so the ladder visibly continues past black.
Appearance
Two registers
The switch at the top of this page runs the app's two skins.
- Iron 鉄Dark, and the default.
- Paper 和紙Light: paper and ink.
A grade is carried by brightness step, ring, shape and label, so a belt reads the same in either.
