Habit Tracker for iOS & Android
Build habits that actually stick.
Atomin is your science-based habit tracker: plan your morning routine, workouts or meditation, build motivating streaks and watch your progress in beautiful statistics – one habit at a time.
Inside the app
A habit tracker you'll actually enjoy opening
Dark design, playful mascots and clear stats: tracking habits made fun – every single day.
The recap view shows exactly how your week went for every habit — day by day, as an easy-to-read progress bar. It's the fastest way to see which routines are already sticking and where you still have room to grow. Small wins become visible right away, and that's often exactly what keeps you going the next day.
Atomin celebrates every completed habit with its own celebration screen, showing your current completion rate as a percentage. If you want, one tap turns that moment into a card you can share with friends. No feed, no pressure — just a nice way to show off a win when it feels worth sharing.
How it works
3 steps to routines that stick
- Create a habit – with a why & a reward
- Choose your habit, your goal ("I'm doing this because…") and a reward. Decide which weekdays it applies to – daily, weekly or fully custom.
- Check it off daily – via widget & reminder
- Smart reminders nudge you at the right time. Check off directly from the home-screen widget – no need to open the app. That's what keeps your streak alive.
- Watch your growth – streaks, trophies, stats
- A yearly heatmap, completion rate and weekly streaks show you in black and white how you're improving. Celebrate finished habits in the trophy tab.
Expert Habit Tracking & Development
Why Atomin sticks where other apps fail
- Science-Based Habit Tracking
- Atomin is built on habit-formation research: small steps, clear triggers, visible rewards. When you create a habit, the app asks for exactly that – no extra ritual to learn first.
- Personalized Habit Tracking Journey
- Whether it's exercise, meditation or drinking water: you set the rhythm, goal and reward yourself – as individual as your day.
- Smart Habit Building System
- Big change rarely starts big. Atomin helps you start with a small, doable version and only scale it up once it feels stable.
- Advanced Habit Tracking Visualization
- A yearly heatmap, completion rate and weekly streaks make visible what otherwise only feels true: that you're improving.
- Share wins, not just checkmarks
- After every completed habit, Atomin celebrates with you and lets you share your completion rate as a card with friends – a small moment that carries motivation beyond the screen.

Habit Tracking Features
Premium Features That Make atomin Your Ultimate Habit Tracking Companion
- Notes for every habit
- Jot down why a day worked or didn't, right on that habit. After a few weeks you'll spot your own patterns without keeping a separate journal.
- Stats that actually help
- A yearly heatmap, completion rate and weekly streaks show you at a glance when you're strong – and when you're not. More useful than a single percentage.
- A dashboard that fits you
- Give each habit its own color so ten or more active habits stay easy to scan, instead of scrolling through a flat list.
- Schedules that move with you
- Set custom weekdays, start and end dates for every habit. A three-week challenge needs different rules than a habit for life.
- One account, every device
- Check off a habit on your iPhone and see it done minutes later on your Android tablet – no manual syncing required.
