Questions

Frequently asked questions about HabitKai.

Is HabitKai free?

Yes — HabitKai is free to download and free to start using from the Google Play Store.

Do I need to create an account?

No. There is no sign-up and no login. You install the app and begin — nothing asks for an email address.

Where is my data stored?

On your device, and only on your device. Habits, tasks, notes and mood entries stay in your phone's own storage and are never sent to a server.

Can I move my data to a new phone?

Yes. HabitKai can export your full history to a file and import it again, so switching phones does not mean starting over.

Does it work offline?

Yes. Because nothing depends on a server, HabitKai works exactly the same with no connection at all.

What can I track?

Recurring habits, one-time tasks and your daily mood. You can view them by day, week or year, and organise them by morning, afternoon or night.

Can I set reminders?

Yes. Each habit and task can have its own reminder schedule, so you are nudged only about the things that matter to you.

Is there an iPhone version?

Not yet. HabitKai is currently available on Android through the Google Play Store.
