Atoms vs Streaks

Atoms

• 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

Streaks

• People who want a simple habit tracker on Apple devices
• Habits the Health app can confirm automatically, such as daily steps
• Buyers who prefer a one-time purchase to a subscription

Atoms

• The web checkout's comparison table gives Free 1 habit and Pro 6 habits; no tier with unlimited habits is listed.
• 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.

Streaks

• Listed only for iPhone, iPad, Apple Watch, Mac and Apple Vision Pro; no Android, Windows or web version is offered.
• The app tracks at most 24 tasks.
• It is a paid download at $5.99; no free version or trial is listed.

Atoms

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.

Streaks

Up to 24 tasks with streaks

Choose or create up to 24 tasks. Completing a task extends its streak by a day, and breaking the chain resets the streak to zero.

Flexible schedules

A task does not have to be daily: set the days it applies to, or a weekly frequency, so that days off do not break the streak.

Health app tracking

Tasks linked to the iOS Health app, such as steps or running distance, are recognized as complete automatically.

Negative and timed tasks

Negative tasks are meant for breaking bad habits, and timed tasks are also supported.

Apple Watch, widgets and Siri Shortcuts

The Apple Watch app has complications and widgets, the iPhone has home screen widgets, and Siri Shortcuts are supported.

iCloud sync and sharing

Tasks sync across your devices through iCloud and can be shared with other Streaks users.
