Habit Tracker — Dark Mode

The same habit tracker, rebuilt for a dark workspace — identical engine, different palette.

If you work in dark mode, a white sheet is the one window that makes you squint. This is that tool with its surfaces, rules and text redrawn for a dark ground rather than colour-inverted, with contrast checked cell by cell so the grid stays legible where a naive inversion turns grey text to mud. Everything it computes, the light version computes too.

WHAT'S INSIDE

Start Here — how the file works and which cells are yours

Habits — start date, up to fifteen habits with a group and a cadence, days elapsed

12-Month Grid — 365 rows dated from your start date, one column per habit

Streaks — marked, current streak, longest streak and completion per habit

Dashboard — overall completion, habits tracked, days elapsed, longest run of any habit

THE PART NOBODY ELSE BUILDS

The measurement, which is the same here as in the light edition. The current streak counts back from your last mark rather than from today, so it does not read zero every morning before you tick. Completion runs against days elapsed since your start date rather than the calendar year. A blank day is a miss and resets the run. What the dark edition adds is that none of it is painful to read at eleven at night — the palette was rebuilt for the ground it sits on, not flipped, and every cell was checked at the contrast the light version meets.
