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.

Habitify

Daily schedule and reminders

Habits are laid out across the day with reminders. Free allows 1 reminder per habit; Plus adds unlimited reminders by time, location or habit stack.

Progress tracking

A calendar, streak counts and completion rates show how consistently each habit is being kept.

Timers, notes and mood log

A countdown timer and text notes with a mood log are free. Pro adds Pomodoro and stopwatch timers with background sound, and notes with images.

Health and fitness sync

Habits can be linked to data from Apple Health, Health Connect, Fitbit and Strava. Health app sync is listed as a Pro feature.

Challenges with friends

Friends can compete in habit challenges, and there are monthly leaderboard challenges.

API, automation and AI tools

Pro includes API access and Zapier and IFTTT connections. The help center also documents an MCP connector for AI assistants such as ChatGPT and Claude.
