Atoms
Official Atomic Habits app for building identity-based habits
What is Atoms?
Atoms is the official habit app for James Clear's book Atomic Habits, published by Atomic Development Inc. Each habit is written as a statement anchored in an identity and committed to a time and place, then logged by pressing and holding its atom. The app adds reminders, daily goals, habit stacks and a Focus Mode, and Pro adds daily lessons and other Mindset content from James Clear. It runs on iPhone, Apple Watch and Android.
Atoms has a free plan. Paid plans start at $4.99 per month, or $39.99 per year (US App Store in-app purchases). See every plan
Good for
- Readers of Atomic Habits who want the book's four laws built into an app
- People who prefer to start with a few small habits rather than a long list
- iPhone users who want to log habits from an Apple Watch
Worth knowing

- Mindset content and the daily lessons from James Clear are marked Pro-only in that table.
- Apps are listed for iPhone, Apple Watch and Android only; the web site sells and manages subscriptions but is not a web app.
- The length of the trial is not stated on the homepage, the support page or the store listings.
Key features
- Guided habit creation
- Each habit is a statement anchored in an identity and committed to a time and place. Suggestions are offered for every segment and can be replaced with your own wording.
- Press-and-hold logging
- A habit is logged by pressing and holding its atom until it fills, or with a + button in Compact View. Earlier days can be logged or undone from the habit's history.
- Daily goals
- A habit can carry a daily target counted in times or another unit such as steps, and it is logged automatically once the target is met.
- Habit stacking and Focus Mode
- Release notes describe habit stacks built from existing habits, and a Focus Mode that plays audio from a Spotify account or from the app's own music library.
- Daily lessons and Mindset content
- The Mindset tab holds articles and a daily lesson from James Clear; a new lesson appears only after the previous one is read. The web checkout lists both under Pro.
- Reminders, widgets and Apple Watch
- Reminders can fire at a habit's exact time or several times a day. The iOS app has interactive widgets, and an Apple Watch app logs habits away from the phone.
