Where it stands: I use the Mac version every day, and the iPhone version is installed on my own phone. I'm polishing it before it goes to TestFlight.

MatrixMemo is a sticky note on your Mac desktop that sorts your to-dos into the four boxes of the Eisenhower Matrix (important / urgent), so they’re always in view and you can jot one down anytime. Everything is stored in Apple Reminders and syncs between Mac and iPhone via iCloud.

Features

  • Docks to the screen edge: on the Mac, drag the sticky note to the edge of the screen and it stays there, sliding out when you need it and back when you don’t.
  • On iPhone, the whole screen is the note: open it and you’re looking at the four-box sticky note.
  • Check things off from widgets: the iPhone Home Screen and Mac desktop widgets let you cross off a to-do directly.
  • Stored in Reminders: your to-dos are Apple Reminders. “Projects,” which Reminders doesn’t have, are kept in the notes field.
