Identity-first self-improvement
One 2-minute action a day, written by AI for the person you decided to become. Thirty days in, you're not holding a streak. You're holding evidence.
Step one happens right now
This is the first question Arc asks. Pick the one that feels most like the real you — your card updates the moment you choose.
Or write your own inside the app.
"Clear your desk. Don't break the chain."
Tasks and guilt. Stop checking boxes and nothing of you remains.
"A disciplined person clears their desk before they leave it."
Every action is written in the voice of your identity. Habits follow who you are — not the other way around.
The daily practice
Each morning, Arc writes one micro-action for your identity and the obstacle you named. Tap "I did this" and your day is banked.
The AI knows your identity, your obstacle, and your last five actions. Don't like today's? Swap it.
One missed day a week is frozen automatically. Keep your streak through real life — Arc even guards it with a 9pm nudge.
Focus sessions with your identity on screen, or 30-day challenge arcs with their own daily actions.
A calm presence…
A calm presence in every room takes one deep breath before checking their phone.

Day 30 unlocks your compass
Six dimensions of who you're becoming — recomputed daily, with a timeline back to day one. This is one user's real shape changing over 32 days.
Tap the days — the shape remembers.
At day 30, Arc holds up a mirror
"Self-doubt was your stated obstacle. You showed up on the days you rated your energy lowest. Self-doubt is not winning."
— a first mirror, written from one user's real 30 days
You are no longer who you were.

Questions people actually ask
It is a habit tracker organised around who you are trying to become rather than a checklist of tasks. Instead of logging "drink water" or "read 10 pages", you name an identity — say, a calm presence in every room — and every daily action is chosen to be evidence for that person. The premise is that a behaviour sticks once it confirms something you already believe about yourself. Here's the longer explanation.
Most trackers ask what you want to do and then hand you a grid to fill in. Arc asks who you have decided to become, then writes one 2-minute action each morning for that identity and the obstacle you named. There is no habit list to build or maintain, and progress shows up as an alignment score, a six-dimension compass and a written mirror at day 30 rather than a wall of checkmarks.
Not yet. Arc is Android only and is distributed through Google Play.
Arc is $49.99 per year, which works out to about $4.17 a month, or $7.99 month to month. There is no free tier and no ads — the subscription is the entire business model. You can cancel anytime from the Play Store and your data stays saved.
One missed day per week is frozen automatically, so a single bad day does not reset your progress. Arc also sends a 9pm nudge to guard the streak before the day runs out.
No. Arc carries no ads, no analytics trackers and no data selling. Because the subscription is the only revenue source, the app has no reason to optimise for your attention. The privacy policy spells out exactly what is stored and for how long.
No. Arc works without one. You only add an account if you want your arc to sync across devices.
Arc is not affiliated with James Clear or Atomic Habits. It shares the identity-first premise that every action is a vote for the person you wish to become, and builds the entire app around that idea rather than treating it as one chapter.
