Get started

1. Sign in with the Google or Microsoft account whose calendar you live in — that connects the calendar in the same step.
2. Connect a task app from the dashboard. Nine apps work today. Each app has a guide below that tells you what to write in a task.
3. Choose which calendars count as busy and which one receives blocks — meetings on any of them are never booked over.
4. Let the first sync run. Every block has a “Why this time” link inside it, which gives the real reasoning and not a summary.
5. Tune the scheduling rules: what goes first, and what happens when something cannot be finished before its deadline.
6. Finish work from either side — tick the task in its app, or use the “Mark done” link in the calendar block.

Set up your task app

Each guide answers the same four questions: how long, how urgent, when due, and how “done” syncs back. Each guide also names the one thing that the app cannot do.

• Todoist

  The best-rounded free option. Todoist gives you real priorities, real due dates, and a duration convention that we add when you connect.

• Google Tasks

  Comes free with your sign-in. When you connect Google Calendar, you connect Google Tasks too. Google does not ask for a second consent.

• Microsoft To Do

  Comes with the Microsoft sign-in. Outlook is the calendar and To Do is the task list. One consent covers both.

• Notion

  Your database and your columns. You tell Diarized once which column means what, and Diarized reads those columns from then on.

• TickTick

  A strong free task app with real priorities. Two properties of TickTick are important to know before your first sync.

• Linear

  Issues from your active cycle, booked around your real meetings. The sprint plan becomes time in your day.

• ClickUp

  The best task data of any source here. ClickUp's estimate is a real field on the free plan, so you write nothing in titles.

• Jira

  Your assigned issues from the open sprint, scheduled into the calendar that already holds your meetings.

• Asana

  Tasks assigned to you in the workspace you choose. Map two fields once, because Asana does not supply them.

More

• Switching from another scheduler — Motion, Reclaim, FlowSavvy and the day planners: what changes, what to move, and when staying put is the honest answer.
• Roadmap — what works today, what we build next, and what we examined and did not build, with the reasons.
• Blog — including how to schedule Apple Reminders yourself with Shortcuts, since no server-side product can.
• Reading — five books on time blocking, each with where it disagrees with what Diarized does.
