About this app

"What did I actually do today?"

The day ends and the same thought returns. You were busy all day, but can't point to what you
accomplished. The to-do list was long, but the important things didn't get done.

It's not because you're lazy. It's because your time had no boundaries.

Timeboxing

Harvard Business Review ranked it the most effective productivity technique out of 100. Bill
Gates plans in 5-minute blocks. Cal Newport plans every evening for 20 minutes.

The principle is simple. Put a boundary on the time you give to each task.

Tbox makes this easy for anyone.

Plan your day in 4 steps

[1] Brain Dump
Get everything out of your head. Tasks, ideas, appointments. No format needed.

[2] Prioritize
Pick your TOP 3. The rest can wait until tomorrow.

[3] Time Blocks
Drag to assign time. Give each task the time it deserves.

[4] Execute
Focus timer turns on. Stay immersed. Done beats perfect.
