Question 1

What is timeboxing?

Accepted Answer

Timeboxing is the practice of assigning a fixed block of time to a task — instead of working until the task is done, you work until the time is up. Each task gets a start time and an end time on your calendar, so your day becomes a series of blocks you can see at a glance.

Question 2

How does the timebox planner work?

Accepted Answer

Tell it when your day starts, add your tasks with rough time estimates, and the planner converts your optimistic guesses into realistic blocks with automatic buffer padding. It then lays out your whole day block by block, showing exactly when you'll finish each task — and when you'll actually be done for the day.

Question 3

Why does the planner add buffer time to my estimates?

Accepted Answer

Because people almost always underestimate how long tasks take — especially when transitioning between them. The buffer (default 30%) absorbs transitions, interruptions, and the gap between your optimistic estimate and reality, so one overrun doesn't collapse the rest of your day.

Question 4

How is timeboxing different from a to-do list?

Accepted Answer

A to-do list tells you what to do but not when. A timebox gives every task a start and end time, which does three things: it makes time visible (crucial if you struggle with time blindness), it forces prioritization because the day is finite, and it gives you a clear finish line so tasks stop expanding to fill available time.

Question 5

Is the timebox planner free to use?

Accepted Answer

Yes. The timebox planner runs entirely in your browser with no account and no signup. Your tasks and settings are saved locally on your device. It's part of a larger set of free focus tools, and premium products are optional extras if you want the full system.
