A habit tracker that draws your habits as one tree. Every marked day grows a leaf, 66 leaves on a branch grow a fruit, and a habit you cut stays on the tree as a stub. The tree stands in a living world — real sun, real moon, real weather. Rain, snow and fog come and go, the seasons turn, and 5,044 stars stand in their true places for your date and hour, worked out from your time zone, not your location. No account, no analytics, no subscription.

I built RIPEN because every habit tracker I tried punished me for missing a day, and none of them showed me the years I had already lived.
So the app draws one tree. A marked day grows a leaf; 66 leaves on a branch grow a fruit, which is roughly how long a habit takes to stop needing a decision. Miss a day and a leaf falls — the second day in a row costs two, the third costs three — but the tree never dies and the branches never shrink. One marked day stops the run. A fallen leaf stays on the ground: the app does not hide the days you missed.
Most of the work, though, went into the world the tree stands in, because a tree you keep for years should live somewhere rather than float on a background. It runs on real time. The sun and the moon are where they actually are, and the moon shows its real phase. Weather comes and goes — rain, snow, thick fog that swallows the distance — and the seasons turn with the calendar, so a winter crown is bare and the birds go quiet when snow lies on the ground.
At night there are 5,044 stars in their true places for your date and hour, each with its own measured colour: Betelgeuse is warm, Rigel is blue. The planets are there and they do not twinkle — a disc an arcsecond wide is not shaken by the air, and that is exactly what tells a planet from a star by eye. The Milky Way lies where the galaxy lies.
All of it is worked out from your time zone alone. The app never asks where you are, and there is no account: the habits, the days and the whole tree live on the phone, and marking a day needs no network.
Happy to answer anything, including what it still gets wrong.
I'm Anton. I design products for a living; RIPEN is mine.
It started with Atomic Habits, and with one idea in particular: a habit isn't what you want to do, it's a vote for the person you want to become. I'm not much of a habit-tracker person myself. What I wanted was something that lives beside you by its own laws — something you can influence but not command, where you can see what your actions did to it.
So the tracker is a tree. One day you keep is one leaf: not a percentage, not a streak number. Sixty-six clean days on a branch grow a fruit, and that fruit is the only colour on an otherwise monochrome tree. Miss a day and the leaf falls and stays there on the ground, because that happened too. Stop a habit and its branch becomes a stub instead of vanishing — it was part of the path.
Far more work went into the world around the tree than into the tracking. Real sun and moon, real weather for your date and hour, and 5,044 stars where they actually are, worked out from your time zone and never your location. Aurora. Fog. A temperature that both the precipitation and the sound layers follow. Lakes that rise after rain. Lightning and thunder on their own schedule. The point was a world that looks alive and surprises you every so often, not a backdrop.
The hardest screen was onboarding. A beta tester told me "I don't get it at all" — the slides were explaining rules in words. I rebuilt it around one example tree growing five days per slide, and over three weeks it went through about twenty rounds of changes, four of them full reworks, each after short interviews with testers from different jobs watching a live build.

It's for people who care less about ticking things off and more about watching something grow.
And the thing I'm genuinely unsure about, which is what I'd like to hear from you: does the living world get in the way of the point? This is a habit tracker where about 90% of the screen is a tree. I can't tell any more whether that's the feature or the problem.
