Habit Arc: Habit Tracker

Yannick Mueller

About this app

Missing a day should not make you want to quit. Habit Arc is a private, offline habit tracker built around getting back to your next repetition.

Mark a habit Done or Missed. An untouched day stays neutral. A miss slows your progress, but it does not erase it. The idea is simple: never miss twice.

Habit Arc helps you build habits you want more of and reduce habits you want less of. No account. No cloud sync. No ads.

Build or reduce habits

Create Build habits for routines you want to grow, or Reduce habits for the ones you want to cut down. For a Reduce habit, add an early warning sign and a replacement action so you have a plan before the moment hits.

A schedule for real life

Set daily, weekly, or monthly schedules and optional reminders. Mark each occurrence Done or Missed, or undo an entry. If you miss one, Habit Arc points you toward the next repetition.

Check in, not just check off

Use a daily check-in and quick journal to note how a habit felt, not only whether you did it. Over time, you can spot patterns in your routines.

See your habits grow

The Growth view shows progress without turning everything into a streak. Your Growth Score combines repetition, consistency, recovery, and automaticity. Habits move through five stages: Seedling, Sprouting, Growing, Established, and Deep Rooted.

Private by design

Your habits, history, reminders, journal notes, and check-ins stay on your device. Habit Arc does not request Internet permission, so it cannot send your data to a server on its own.

- Works fully offline
- No account or sign-up
- No ads, analytics, or trackers
- Export and restore your own backup whenever you want

Habit Arc is for people who want a calm, private habit tracker and a practical way back after a setback. It does not offer social accountability, competitive gamification, or cross-device cloud sync.

Build habits that survive a bad day. Never miss twice.

What’s new

Tap habit reminders to open the relevant entry in the app. Creating your first habit is now simpler, and localized buttons are easier to read on smaller screens. Weekly check-in and journal sheets now close reliably when dismissed.
