Atoms
Atoms is the official Atomic Habits app from James Clear, built on the book's four laws of behaviour change — identity-based habits, right-sized starts, personalised reminders and daily lessons — to help you build habits in a few minutes a day.
- Grounded in a proven, widely trusted behaviour-change method
- Identity framing and right-sizing help habits actually stick
- Daily lessons coach you, not just track you
- Focused and uncluttered, doing one thing well
- The 'AI' is light — adaptive design, not a generative model
- Narrow: not a task manager, calendar or notes tool
- Mobile-first, without a broad cross-platform suite
