How it works

Press harder with a pen for a thicker line.
Two fingers move and zoom the board. Tap with two fingers to undo, three to redo.
Your pen’s eraser (or its side button, held down) erases whatever tool you’re on. The eraser takes away whole lines it touches.
Tap a tool twice on a narrow screen for its colours and sizes.
With a keyboard: P pen, H highlighter, E eraser, 1–6 colours, [ and ] size, F show it all, Ctrl + Z undo, Space + drag to move.
Add it to your home screen to use it full screen, with no address bar. It works offline.
