A5 (148 x 210mm). Small enough to carry everywhere, big enough that you're not writing in the margins. Each notebook is 64 pages.

Instead of the same daily page over and over, there are sixteen daily layouts grouped into four families. Work front to back for the whole rotation, or turn straight to whichever one suits the day — both are right. Every layout has its instructions printed on it, so one you haven't used before is never a puzzle.

Then you missed a few days. The planner is undated, so there's no guilt-inducing row of empty pages staring at you. Pick it up when you're ready. Skip a weekend. Skip a week. It doesn't care and neither should you.

It's designed for ADHD brains, but anyone who finds traditional planners boring, rigid, or guilt-inducing tends to love it. If you've ever abandoned a planner because it felt like homework, this was made for your brain too.

The inside layouts are the same across all {count} colours, so functionally, no. But emotionally? Absolutely. The colours and personalities are there because picking something that feels like you makes you more likely to actually use it. And that's the whole game.

That depends entirely on how you use it. The daily pages drive the book rather than a calendar, so it isn't tied to a month — some people fill one in a few weeks, others keep one going far longer and reach for it on the days that need it.

When you finish one, start another. Same colour if you've found your match, or a different one if you fancy a change. Either way you never have to carry the weight of an 18-month planner you stopped using in March.

Yes. Our refillable folios are designed to hold Fast Brain notebooks (and our other A5 ranges). You can lace multiple notebooks in at once and swap them out whenever you like. Here's how to set one up.
