This is a working preview — tap a habit to log it.

Every habit comes alive

Progress you can see
filling up.

Each habit gets its own illustration that moves as you log. Hydration fills a bottle. Steps climb a trail. Sleep grows a full moon. It’s the reason people open the app — and keep coming back.

Water

The bottle fills, sloshes and bubbles toward your goal.

Steps & walks

A trail climbs to the summit. The flag goes up at 100%.

Training

Every minute feeds the flame.

Reading

Lines of text appear as the pages add up.

Sleep

A crescent waxes into a full moon, with stars.

Early mornings

The sun rises over the ridge.

Quitting things

No sugar, no scrolling: the shield holds and fills.

Calm

Meditation breathes and ripples outward.

Built for real days

01 · One-tap logging

Log it in a second.
Or tell the whole story.

Tap + on a habit and you’re done. Want more? Open it to add exactly what you did, with quick amounts that fit the habit — a glass, half a litre, ten minutes — and a note for future you.

  • Partial effort counts: 2 of 3 litres is 67%, not a fail
  • Finished habits tuck away, so the list gets shorter all day
  • Finish everything and the whole day celebrates with you

04 · The daily debrief

How did today feel?

Pick a sky, write two honest lines. Prompts like “What worked” and “Tomorrow I’ll” get you started. Over a season, you’ll see what your best days have in common.

No account to create, no server, no ads, no analytics SDK. Your habits, notes and reflections live in the app on your device — and you can clear them any time.

Before you begin

A few things worth knowing.

What is a winter arc?
A winter arc is a season of intentional self-improvement, usually 1 October to 31 December, when you commit to a few habits — training, sleep, reading, less scrolling — and finish the year stronger. The Winter Arc gives that idea a home: your own rules, one-tap logging, a daily debrief and a record of the whole season.
When does the winter arc start and end?
Most people run their winter arc from 1 October to 31 December. The app defaults to that season — starting today if you’re joining late — but you can start on any date and choose 30, 60, 90 days or any length up to a year.
What are the winter arc rules?
There are no official rules. Pick three to five habits you can realistically keep, set a target for each, show up on the days you planned and reflect on how it’s going. Small and consistent beats extreme and abandoned.
What happens if I miss a day?
Nothing resets. Your history stays, partial effort counts toward amount habits, and you can fill in a day you forgot to log. There are no streaks to break — the score reflects what you recorded, not your worth.
Is it free? Do I need an account?
Yes, it’s free, with no ads or subscriptions. Winter Arc Lite needs no account. Everything is saved on your phone; uninstalling the app removes it.
How do I install it?
