Track quitting progress, milestones, journals, and recovery reminders.
New in version 1.1.50
• Fix F-Droid lockfile reproducibility
• Harden Patrol tests against timing
Track the habits you want to quit and celebrate every step forward.

Quitter is a private habit and quitting tracker for people reducing or stopping smoking, vaping, alcohol, drugs, adult content, social media, and other personal habits. Set your start date, follow milestones, reflect in a journal, and keep your progress visible day by day.

SUPPORT YOUR QUITTING JOURNEY

• Track 13 built-in habit and addiction journeys
• Create custom trackers for any habit you want to change
• Follow cited, research-informed recovery milestones
• Record daily thoughts and feelings in a private journal
• Receive milestone reminders and progress notifications
• Personalise colours, themes, and optional features

PRIVATE AND OFFLINE

Quitter does not require an account or internet connection. Your progress and journal entries stay on your device. The app is open source, contains no ads, and does not track you.

Milestones are educational information drawn from sources such as public-health organisations and peer-reviewed research. Quitter is not medical treatment, diagnosis, or professional advice. For medical support or concerns about substance use, contact a qualified healthcare professional or local support service.

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
