Just me
A habit tracker that asks nothing of you.
No account, no email, no sync to set up. Open it, add a habit, tick it. It works offline and stays on your phone unless you invite someone in.
Free. Add it to your Home Screen and it feels like an app.

How was today?
How it goes
- 1
Streaks with forgiveness
One miss a week can count as skipped. The streak is there to help, not to judge.
- 2
Mood and energy
Two taps in the evening. After a few weeks the insights show what moves them.

Company, later
When you want it, turn your room into one for two or a few. Your history stays exactly as it is.
Who it is for
One room per group of people. Be in as many as you like; nothing crosses over between them.

What you get
Yours, each of yours, or anyone's
Keep a habit to yourself, give everyone in the room their own copy, or share one that counts when anyone does it.
Streaks that forgive
One missed day a week can count as skipped, so a bad Tuesday does not erase a good month. Per habit, your choice.
Mood and energy
Two taps in the evening. Over weeks you see what moves them, and so can the people you choose.
Pings and reactions
A nudge when your partner is behind, a reaction when they are not. Nothing to type.
Off-schedule and catch-up
Did it on the wrong day? Count it anyway. Missed one? Add a reason and move on.
A weekly look back
Every week a short summary of what went well. The assistant that writes it stays off until you turn it on.
Private by construction
- No account, no password. Your phone holds a key; a 12-word phrase or an optional email gets you back in.
- A room opens only with its link. There is no directory, no search, no public profile.
- Offline first. Every tap is saved on the phone and synced when you are back.
- Your data, your call. Export it as a file or delete it, in Settings, at any time.
- Runs on Cloudflare under the GDPR. The optional assistant runs there too, not at another company.
- Free while it is small. No ads, no selling of data, no growth team.

Questions people ask
Can I use Jatkuu on my own?
Yes. Pick "Just me" when you start. You get the same habits, streaks with forgiveness, catch-up reasons, mood and energy, insights and the weekly summary, without anyone else in the room. When you want company, the Room tab offers to turn it into a room for two or a group; your habits and history stay exactly as they are.
How does my identity work, and why is there no password?
When you first open Jatkuu, your device creates a key pair. The public key is your identity in a room; the private key never leaves your device and signs every change you make, so nobody can act as you. There is nothing to log in to, so there is no password to remember or leak. Your backup is a 12 word recovery phrase that you can show, copy or save as a file in Settings.
What happens if I lose my recovery phrase?
If you lose both the phrase and the device, and you did not add a recovery email, that identity is gone. We cannot recover it because we never have the phrase or the private key. Your partner can invite you into the room again with a fresh identity, but your history stays attached to the old one. Write the phrase down or save it in your password manager while you still have the device.
Does Jatkuu work offline?
Yes. Every check-in is saved on your device first and shows up immediately. When you are back online, Jatkuu syncs your changes to the room and pulls in your partner's. Two devices editing at the same time merge cleanly; the latest change to the same item wins.
Start today. Invite tonight.
A room takes a minute. The first habit takes ten seconds.
