A project tracker that works like the paper quad grid it replaces. One sheet, four boxes you label yourself, one thing marked next in each, and a fresh sheet each morning if you want one.

A client, the house, the kids, a side project. Whatever your week is actually divided into. No imposed categories, no urgent versus important.
Each box has at most one task marked next. Marking another clears the last one. Four boxes, four next things, and that is the plan.
Cross things off all day. The next morning the sheet asks whether to put them away. Say yes and they go to history, by day, where you can always look them up. Open tasks stay right where they are.

Swipe between the four boxes, or stack them in one scroll. Tap the dot on any task to make it next. Projects that are not on the sheet wait on the bench with their tasks intact.
Sign in with Apple, Google or an email link. No password, ever. It syncs between your phone, your tablet and the web.
The sheet, the boxes, next, the bench, the morning reset and history are free for good. Plus adds the things a paper grid never could.
Everything you need to run your week the paper way.
For sharing a box with someone, and for running more than one sheet at once.
Plus is not on sale yet. Shared boxes, templates and extra sheets are free to everyone while we finish it. Sharing a box never costs the other person anything.
The matrix sorts your life into urgent and important. You already know what is urgent. What you need is to remember which page you wrote it on.
