Sign in
Continue with Google or Apple, then the same lists everywhere.
Every task has an effort in minutes. That one idea turns a to-do list into a picture of your day.
Three rings show the work you finished today, this week and all time, plus time left, due today, overdue and your streak.
This week against last week, a 14-day activity grid, per-list progress and upcoming deadlines.
Colored lists as columns on one board. Drag tasks between them, or pop a list out into its own window.
Add tasks inline with a due date, effort and list. Undo anything. Overdue? Push it a week; it counts as a strike.
A day, six hours and an hour before something is due. On Android, even when Kailos is closed.
Export a full backup or a Markdown list, and import it anywhere.

Google Tasks keeps a list. Kailos gives every task a length in minutes, so it can show the time you actually finished (rings, streaks, insights, a weekly Wrap), split big projects into daily sessions and remind you before things are due. Your data is never used for advertising. See the full comparison.
Yes, a Google or Apple sign-in the first time you open it. After that it opens straight into your lists and works offline, syncing when you're back online.
Only your email, to tie your data to you (Apple may give us a private relay address instead). It never reads your mail, contacts or files.
The newest edit wins, on every device.
Nothing is lost. Your library links to your account the first time you sign in.
Kailos checks when it opens and from the menu. Your data is stored separately, so updates never touch your tasks.
It blends kairos (καιρός), the right or opportune moment, with telos (τέλος), the end something is working toward. The app is about doing the right thing at the right time, with every task aimed at a goal. It was called Tasker before.
Yes, for Android and iPhone. Both are in beta, and you can join the beta to try them.
