idea: keep the home page to three sections…
or drag one in yourself

Give a line a #type and it becomes a thing.

A type brings its own fields, icon and views. Pick one and watch the line change.


      

    

  


  

    

      
One type, many views.

      
Every type opens as a table or a board of its objects. Tick a task in one view and the other already knows.

Try it: switch views, then tick a task.

  


  

    

      
Your days, laid out. Move things by dragging.

      
Day, three days or a week. Drag a block to another time or day and the task's date follows. Calendars from Google or Outlook sit beside your own.

Try it: drag a block, or focus one and use the arrow keys.

  


  

    

      
All of it, in one window.

      
Today, your tasks, the calendar, your people and the graph, side by side in one app. Click around the sidebar.

Letting go should feel as good as finishing.

      
Not every open item is a to-do. Strike a task with a pen line when you won't do it, scratch out a thought you're done with, and move on. Nothing hangs around as guilt, and nothing is lost: it is all still in your files.

Five things settled today? Not yet.

      
Try it: tap a box to strike a task, or tap the note to scribble it out.

    

  
    

  


  

    

      
Every note is a star. Today is the sun.

      
The note at the top of this page, charted like a page from an old star atlas. Link someone in it, or give a line a #type, and the new star is engraved onto the plate. Things you link often grow brighter.
