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.
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.

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.
