How we grade them
| 3.0GPAAtomsVery good | 3.2GPAHabitKitVery good | |
|---|---|---|
| Value for money | BPro is $4.99 a month or $39.99 a year, about 33% less, which is ordinary money for a habit app. It buys 6 habits plus James Clear's daily lessons and Mindset content. Six is the ceiling, mind: no plan with unlimited habits is listed. | APro comes by the month, by the year or once for life. The US App Store lists Lifetime at $14.99 and $29.99, and a year from $5.99 to $24.99. Every one of those is cheap for a habit app. The app shows which price applies to you. |
| Free plan and trial | BFree gets you 1 habit, with suggestions and an accountability partner. Just the one! There's a trial of Pro with no commitment that drops you back to free when it ends, though nobody says how long it runs. | BUp to four active habits with no time limit, with all three tracking types, notes, categories, quit habits and automatic daily backups. But it's one reminder per habit, and widgets, charts and export all need Pro. Four fills up fast. |
| Features | BGuided habit statements tied to an identity, a time and a place, daily goals counted in times or units like steps, habit stacks, a Focus Mode that plays from Spotify, reminders, widgets and an Apple Watch app. The gap is the cap: 6 habits at most, even on Pro. | BA year-long tile grid for every habit, tracked as a tick, a count or a measured amount, with streaks against daily, weekly or monthly goals. Seven iOS Shortcuts actions too. But there's no skip day or streak freeze, and nothing syncs between devices. |
| Ease of use | A4.8 from about 10,700 App Store ratings. The app suggests wording for every part of a habit, and logging is just pressing and holding its atom until it fills. | A4.8 from about 2,400 App Store ratings. There's no account to create and it works offline, so there's nothing standing between installing it and logging your first habit. |
| Platforms and integrations | CiPhone, Apple Watch and Android, with Spotify for Focus Mode. That's phones and a watch only. The website sells and manages subscriptions, but it isn't a web app. | CiPhone and Android only, with Siri and iOS Shortcuts on the iPhone side. The help center says there's no Apple Watch app, and no web or desktop version is listed. Your data stays on the one phone. |
| Best for | readers of Atomic Habits who want a few small habits | seeing a year of each habit as a grid of tiles |

Worth knowing
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.
HabitKit
- The free version stops at four active habits; widgets, charts, extra reminders, and export and import need Pro.
- Nothing syncs between devices: moving to a new phone means exporting a file and importing it, and export and import are Pro features.
- The US App Store lists several amounts for each Pro period, such as $0.99, $1.99 and $4.99 for one month; the app shows the price that applies.
- Listed for iPhone and Android only. The help center says there is no Apple Watch app, and no web or desktop version is listed.
Key features
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.
HabitKit
- Tile grid for every habit
- Each habit gets a year-long grid with one tile per day and one column per week, and the dashboard offers three views for seeing all habits together.
- Yes/No, Count and Measure tracking
- A habit can be a daily tick, a whole-number count or a measured amount with a unit and up to three decimal places. Counts and amounts use a daily goal or, for quit habits, a stay-below limit.
- Streaks and flexible goals
- Streaks follow a daily, weekly or monthly goal, such as 3 times a week or 20 times a month, so planned days off are not misses. There is no streak freeze or skip day.
- Home screen widgets
- Widgets on iPhone and Android show habit grids and let you log a habit without opening the app. They are part of Pro; without it a widget shows a padlock.
- Siri and iOS Shortcuts
- Seven iOS Shortcuts actions log amounts and notes, edit past days, read progress or open a habit, and can be run with Siri or from automations.
- On-device data and backups
- Habit data stays on the phone with no account. The app keeps seven daily backups that are free to restore, and Pro adds export and import of one JSON file.
