Kairos
Your tasks in the right order, fitted into your day. No account, no network.
New in version 3.0.0
Kairos 3: rewritten as a native app, instant start, no network permission. Installed over Kairos 2, it brings over your tasks, notes and timer sessions. Day view ordered by score, Week, Notes, Statistics, timer with notification and alerts even when the app is closed. Updates now come through F-Droid, IzzyOnDroid or a new APK. TimeTree and GitLab import are removed.
Kairos puts your tasks in the order to do them and fits them into the gaps of your day, at the right time.
An order you can explain
Each task gets a priority score (WSJF): its value (priority P0, P1 or P2, plus the urgency of its deadline) divided by its effort in points. Small and important goes before big and distant; an overdue task always comes first. “Why this position?” shows the calculation in one tap.
A realistic day
Capture without friction (GTD)
An idea? A note. A task? A title is enough: it waits in “To process” until you give it a priority and a size, one tap each.
Real time
A timer per task, with an ongoing notification; alerts when you go past the estimate, forget a running timer or need a break, even with the app closed. Statistics compare your estimates with the time actually spent.
Your data stays with you
Kairos is also available for Windows, Linux and macOS, and in the browser. Free software under the MIT licence, in French and English.

A realistic day
- Tasks are placed around your meetings, with a buffer after each one.
- Deep-work slots are protected; in the afternoon, complex tasks give way to lighter ones.
- Fixed times, recurring tasks (daily, weekdays, weekly, “on the 23rd of the month”), dependencies between tasks, subtasks, French public holidays.
