Put your tasks into time.
That's timeboxing. That's all there is to it.
The one principle the world's top performers share.

— Harvard Business Review, #1 Productivity Technique


01Today View

The essence of a day.

A 9-slot grid that distills each day to its essence.
Morning, afternoon, evening — priorities made crystal clear. Physical constraints force choices, and those forced choices fuel deep focus. Anything beyond 9 slots belongs to tomorrow.


02Identity & Goal

Execution without a compass
is just wandering.

Go beyond simple to-do lists. The Goal Compass at the top constantly reminds you of the goals and identity you're working toward. True focus begins when you never forget who you are and where you're heading.


03Integrated Rhythm

Work and life on a single timetable.

Morning reading, school drop-off, workouts — recurring todos fill the timebox first. Fill the remaining slots with today's unique tasks. Within the physical constraint of 9 slots, you can balance work and life priorities.


04Contextual Clarity

Distribute energy
by project.

From personal exploration to core work projects, group every task by context. See exactly where your time goes and how much. Complex, tangled work becomes clear when organized project by project.


05Feedback Loop

Data
doesn't lie.

Daily and weekly retrospective archives become the most refined data for growth. Go beyond mere 'done' records — analyze completion rates, focus time, and procrastination patterns. The more you use 9todo, the better you control yourself.

You spend hours tweaking Notion templates, list 30 tasks in a spreadsheet and feel the pressure, then push everything to tomorrow. 9 slots is all you need. 9todo's promise.

not everything.
just today.
