Halfwise task screen: a 2×2 matrix with importance and urgency gauges

An Eisenhower Matrix to-do app with one extra rule: only half your tasks can be High.

High means half, at most.

For both importance and urgency, only half can be High. To add to a full row or column, move something else.

Example with 8 open tasks

Try the swap.

Do now is full. How do you fit in a new task?

Priority is relative, not absolute.

“Everything matters” means nothing has been decided. Priority only appears when you compare one task with another.

A standard Eisenhower Matrix

Overflowing
  • Do now 15
  • Plan 8
  • Quick tasks 2
  • Later 1
With no limit on how many go in, Do now balloons fast.

Halfwise

  • Do now 3
  • Plan 1
  • Quick tasks 1
  • Later 3
High is capped at half. With 8 tasks, they naturally spread out like 3 · 1 · 1 · 3.

Six ideas behind it

  1. Separate important from urgent

    Eisenhower Matrix

    Treat “it matters” and “it’s due” as two different questions.

  2. High means half

    Forced Distribution

    Decide in advance how many can sit at the top.

  3. Decide against the others

    Ipsative Measurement

    Rank tasks against each other, not by a score on their own.

  4. Choose A or B

    Pairwise Comparison

    Put two side by side and the choice gets easy.

  5. Slots have a cap

    Kanban WIP Limit

    Hold less at once, and work starts to flow.

  6. To add, remove something

    Opportunity Cost

    Choosing one thing means not choosing another.

Add screen: pick one of four quadrant buttons

Add in one tap

Type a title, tap a quadrant. You see whether there is room before you tap.

Swap screen: the new task next to the existing ones

Decide by swapping

If a quadrant is full, tap the task that moves out. Undo is right there.

Matrix screen: swipe right to complete, left to delete

Finish anytime

Swipe right to complete, left to delete. No confirmations, no blocking.

Today screen: tasks due today and Do now

Just today

Do now and everything due today, in one list. Priorities never change on their own.
