Run your day off one board.

Kairo OS is a free time blocking app. Tasks, habits, goals and your calendar land on one live schedule, so the plan stays in front of you instead of in your head.

An example day, running on your clock: 09:40

A goal only moves when it reaches your day

Most tools keep goals, tasks, habits and your calendar in separate places, so the long-term things quietly never get time. Kairo OS runs them down one chain. Here is a worked example of both halves.

One board instead of five apps

Most productivity setups are held together with tape: a to-do list here, a habit tracker there, a calendar somewhere else. Kairo OS replaces all of it with one board that holds the whole day.

Works with your AI assistant

Manage your plan by chatting with Claude or another AI assistant: create tasks, log habits, and check goals without opening the app.

Real time blocking

Drag any task onto your schedule. It respects existing meetings, avoids overlaps, and pushes back if the day is already full. New to the method? Read the time blocking guide.

Habits that survive busy weeks

Health, learning, fitness: habits stay visible next to your plan, with streaks and history so you actually notice the trend.

Goals that show up daily

Track long-term goals with simple progress markers, right alongside the tasks and habits that move them forward.

Two-way Google Calendar sync

Blocks you schedule appear in Google Calendar. Meetings from Google appear in your plan. Both stay in sync.

Flexible when plans change

Drag tasks to a new time whenever your day shifts. The schedule updates instantly, with no starting over.

Who Kairo OS is for

  • People with ADHD who need the plan visible, not buried in a list. Read the ADHD daily planning guide.
  • Founders and makers juggling deep work, meetings and personal goals.
  • Students who want structure without maintaining five different apps.
  • Anyone who’s tired of ending the day wondering where the time went.

Your data, and why Kairo OS asks for it

Kairo OS asks for the least it can and says plainly what each thing is for. There are no analytics, no advertising and no trackers inside the app, and your data is never sold. These public pages count visits with Google Analytics, only if you allow it.

  • Your Google account name, email and picture

    Required to sign in

    To sign you in and show whose board you are looking at. Kairo OS never sees or stores a password.

  • The tasks, habits, goals and lists you create

    Created by you

    This is the board itself. It is stored so your plan is still there tomorrow, on any device.

  • Events on your Google Calendar

    Optional, only if you connect it. You can disconnect any time.

    To show commitments you already have on your timeline, so scheduling a task avoids a clash, and to write blocks you schedule back to your calendar.

  • Access for an AI assistant

    Optional, and off until you authorise it

    If you authorise one, it can read and change your tasks, habits and goals on your behalf, so you can plan by chatting instead of opening the app.
