Plan in the morning, close the day at night.
Every morning you get three lines, and that's the whole list. Try to squeeze in a fourth and notfour quietly says no. Whatever didn't make it can wait for tomorrow.
Plan your three before the day starts. Whenever you like, write down what actually happened, a line or a page. The two sit side by side, and the journal never rewrites your plan. With Pro, add up to four photos and a voice note to each day.
Pro
Tell it what you're aiming for and by when, say a 10k by 29 November. notfour maps out the weeks in between and fills each day's three with the next step. One line on Today tells you whether you're on track, and if you slip, it suggests a new route from where you are. Your first plan is free.
Pro
notfour reads back your last seven days and writes you a few honest lines about what got done and where it slipped. Underneath, the week sits as a row of dots, one for each thing. Share it as an image if you like. The weekly note comes with Pro.
15 of 21 done. Thursday got away from you, and you were straight back on it Friday. Monday, Wednesday and Saturday, all three done.
You don't need an account to start. Nothing you write leaves your phone unless you export it, switch on sync or ask the planner for something. Even then, only what that one thing needs is sent, and the planner's share is never used to train a model.
The three slots and the journal cost nothing. Goals, photos and voice notes come with Pro.
