SketchBoard: Whiteboard

An infinite canvas for thinking with a pen.

Whiteboard is a drawing and note-taking app for Android phones, tablets and stylus devices. Pan and zoom as far as you like, sketch with pressure-sensitive ink, and keep every board on your own device.

WRITE AND DRAW
• Nine brushes — pen, ballpoint, fountain pen, marker, highlighter, pencil, calligraphy, paintbrush and neon
• Pressure, tilt and speed shape every stroke
• Adjustable stabiliser smooths a shaky hand
• Three erasers — whole stroke, precision, and anything you touch
• Full palette with HSV picker, opacity, eyedropper and recent colours
• Unlimited undo and redo, plus two-finger tap to undo and three to redo
• Stylus-only mode so your palm can rest on the screen

BUILD DIAGRAMS
• Fourteen shapes — rectangles, arrows, diamonds, cylinders, callouts, clouds, stars and more
• Smart connectors that stay attached when you move the things they join
• One-tap mind-map layout
• Text boxes, sticky notes, and sixteen quick stamps
• Shape recognition snaps a rough sketch into clean geometry
• Symmetry mirrors every stroke as you draw, up to twelve-fold

ORGANISE
• Multiple pages per board, with a page manager
• Layers with opacity, visibility, lock and reorder
• Eleven templates — kanban-board, meeting notes, SWOT, retro, weekly planner, storyboard, mind map, Cornell notes and more
• Nine paper styles — grid, dots, lined, ruled, isometric, graph and music staff
• Select, move, scale, rotate, group, align, distribute, and tidy up in one tap

HANDWRITING AND TEXT
• Turn handwriting into typed text
• Pull the text out of any photo or screenshot
Both run on your device. Your writing is never uploaded.

PRESENT AND SHARE
• Presentation mode turns your pages into slides
• Stroke replay plays a board back as a time-lapse
• Export PNG, PDF and SVG, up to 4x resolution
• Import a PDF and annotate straight onto it
• Print any page
• Back up a whole board to a single file and restore it on another device

WHITEBOARD PRO
• Voice notes recorded straight onto the board
• Screen recording to MP4
• Unlimited boards, pages and layers
• Every brush, paper and template
• PDF and SVG export, at up to 4x, with no watermark
• Six accent colours
• No ads

The free tier is a real app, not a trial: five boards, three pages each, two layers, every colour, every eraser, unlimited undo, connectors, mind maps, OCR and PNG export — with no time limit.

PRIVATE BY DEFAULT
There is no account and no sign-in, because there is nothing to sign in to. Your boards are stored on your device and we never upload them. Handwriting recognition and text extraction both run locally, so the app keeps working with no network connection at all.

Pro is available as a monthly or annual subscription, or a one-time lifetime purchase. The free tier is supported by ads — never on the canvas while you are drawing.
