Todoi

A free to-do list app that runs in your browser tab

Todoi holds one project in three views - a list, a board, and a calendar - over the same tasks. There is no account and no server: what you type stays in this browser tab, and closing the tab ends the session.

The workspace itself needs JavaScript to run. The pages below do not.

About Todoi - what it is, and what it deliberately leaves out.
How to write a good to-do list - a practical, tool-agnostic guide.
Free to-do apps, compared - twenty-two free task managers grouped by who they suit, plus six that only look free.
One project, three views - why each view shows what it shows.
