Getting started.

The first card on the shelf. Press it and a fresh board opens.

Tap a deck. It opens where you left it, fitted to the screen.

Press the loupe and type a word. It finds decks by name and by what is written on the cards.

Press New Folder, give it a name. Press Edit, then Move on a deck — or just drag the deck onto the folder. Main is home: decks start there, and dragging one onto the Main pill takes it back out.

Press Edit, then Rename on a deck or a folder, and type over the name.

Press Edit, then the bin on a deck. It goes to the trash. A folder goes with everything in it.

Choose Trash in the Filter menu. Restore brings a deck back; a folder comes back whole, and one deck out of a trashed folder lands in Main. Anything left there goes for good after 30 days.

Your plan, the cancel link, export everything, delete the account.

A tray opens under the button: Add, Paste, Clone, Shape, Color and Default. Add puts a card in the empty space nearest the middle of the board; Paste makes one holding what is on the clipboard. Tap the card and write.

Tap a card and type. Edit a filled card; the old words stay struck through underneath.

Hold the hand chip on its corner and drag. Dragging the card works too.

Line on the rail opens a tray: Add, and what the next line looks like — its type, its fill, its thickness, its color and its ends; with a line selected, the same rows change that line. Add arms the tool: press one card, then the other, and the line is drawn between them — it stays armed for the next. Or draw it on the empty board: press and drag, or tap where it starts and tap where it ends. A line can stand on its own, and either end can be moved onto a card later. Or pull one out of the chip under a card.

Tap a card, then Card on the rail: Shape and Color hold the border, the border color and the card color, each on its own page.

Words anywhere. Tap a card, then Note: its font, size and text color. Add, in Note's tray, puts a note on the board with no card under the words; Paste makes one from the clipboard.

Add chooses an image, Paste takes the one on the clipboard — it lands on its own on the board. Drag it onto a card or a note and it goes inside; drag a picture out of a box and it stands on its own again. Two taps on an image bring out its corners, Copy and Delete.

The board's own color and texture — dots, a grid, checks or plain, with a size and a color. Follow theme, on, lets light and dark paint it; a color you set stays.

One tap on a card and its handle is on the lower right corner. Pull it and the other three come out; the tether below spins it.

Press Pan, then Select. Drag a box around cards and lines; move or resize them all at once.

More, then Undo — or ⌘Z anywhere. Undo covers everything. Nothing asks twice.

It saves itself. Watch Saved under the map, bottom right; there is no button. With no connection it reads Saved on this device: what you make is kept there, the app still opens and works, and it is saved the moment you are back.

Back to the shelf. The board is already saved.

Right-click anything — a card, a note, an image, a line, or the board itself — and a menu opens on it. On a phone it is a press and hold. What it offers is what that thing can do; the bottom four are always Cut, Copy, Paste and Delete, with Undo and Redo above them. Some things are only here: Select All, adding a card, a note or an image next to where you pressed, and swapping one picture for another.
