About 1-3-5 Go

1-3-5 Go is a daily planning tool built around the 1-3-5 rule: pick one Big task, three Medium tasks, and five Small tasks — nine things, no more — and that's your day. The limit is the point: it forces you to decide what actually matters instead of stacking an endless to-do list.

There's no sign-up. Click once and you get a private board that lives for 48 hours — long enough to plan today and tomorrow, short enough that it doesn't turn into another abandoned app.
