Folio is a board for the Mac where a whole project fits on one sheet. Notes, lists, colours and arrows, side by side. Under half a megabyte, built only with what macOS already has, and no account: your boards stay on your Mac.
An endless sheet. Two fingers to move, pinch to zoom. It stays smooth with ten thousand cards.
Things you can hold. Cards lift when you grab them and settle when you let go.
Light and dark. Follows your Mac, and both are drawn with the same care.
