Winter Arc: Habit Tracker

Winter Arc: Habit Tracker turns the last stretch of the year into one finite challenge.

Pick a hard start and a hard end. Choose three to five pillars — the areas you
actually want to move — and put a few daily non-negotiables under each. Then
show up. Every day is binary: done, or not.

Ninety days later you come out the other side, carrying momentum into January
instead of writing resolutions from a cold stop.

HOW IT WORKS
• Set your dates. Ninety days by default, or any span you choose.
• Choose 3–5 pillars, with one to three habits under each.
• Check them off daily. No half marks, no partial credit.
• Watch the arc fill in.

CHOOSE YOUR RULES
People don't all fail the same way, so you decide what a missed day costs.
• Streaks — consecutive days where you completed everything. Simple and strict.
• Consistency Score — the percentage of habit-days you completed against a
target you set. Forgiving of the occasional miss.
• Grace Days — a fixed budget of missed days. Spend them all and the arc is
failed. You set the budget.

SEE THE WHOLE ARC
• A heat map of every day, so the whole arc is one picture.
• Your consistency score, longest streaks, and a breakdown by pillar.
• Tap any past day to see exactly what happened.
• Weekly reflections, and a closing reflection when the arc ends.

WHEN YOU MISS A DAY
Missing a day isn't a crisis and the app doesn't treat it like one. You get one
quiet note, the reason you started, and a clean slate. Run out of grace days and
you choose what happens next: keep going with the arc marked failed, or restart
with the same setup.

BEFORE AND AFTER
Add a photo at the start and another at the end, and see them side by side. Both
stay on your device. Entirely optional.

ON YOUR HOME SCREEN
A widget shows the day you're on and how many habits are left, and updates as you
check them off.

PRIVATE BY DEFAULT
No account. No sign-in. No analytics, no advertising, and no third-party code of
any kind. The app has no networking at all, so nothing can leave your phone even
by accident. Everything lives in the app's own storage, and Reset app data erases
all of it.

Winter passes either way. Finish the year strong.
