Time blocking app

The time blocking app that does the blocking for you

Time blocking works. Doing it by hand every morning doesn't last. Syna³ blocks your week automatically and keeps it blocked as things move.

Free forever to plan · no credit card · paid plans start with 14 days free

Automatic time blocking, not drag-and-drop homework

Give a task an estimate, a priority and optionally a deadline. Syna³ finds a slot inside your working hours, leaves the buffer you asked for, and blocks it. A two-hour task with a one-hour minimum block can be split across two mornings; a quick one fits between meetings.

  • checkBlocks placed most-urgent first, never double-booked
  • checkMinimum and maximum block lengths, buffers and working days
  • checkRecurring tasks that re-block themselves when you complete them
  • checkPin any block to hold it exactly where it is

When the day changes, the blocks move

A meeting lands on top of your deep-work block? Syna³ re-plans around it on its own. If something can no longer make its deadline, it tells you — it doesn't quietly drop the block off the end of the week.

Free, and useful in the first minute

The planner — automatic time blocking, the calendar, projects and saved views — is free forever, and it works before you connect any calendar. Add a few tasks and watch the day arrange itself.

Questions

Is there a free time blocking app that schedules automatically?

expand_more

Yes — Syna³'s free plan includes automatic time blocking with priorities, deadlines, buffers and working hours. No credit card, and it isn't a trial.

Does it sync with Google Calendar?

expand_more

Yes. It reads your meetings so blocks land around them, and writes the blocks back to a dedicated Google calendar so they show up everywhere you look at your schedule.

What's the difference between time blocking and timeboxing?

expand_more

Time blocking reserves calendar time for a task; timeboxing caps how long you'll spend on it. Syna³ does both: each block is reserved time, and your estimate is the box.
