Whiteboard turns the Horizon 2D window into a real drawing surface — sketch with the pen tool, drop sticky notes, build shapes, and connect ideas with arrows and frames. Free, private, and fully offline.
A single vertical rail holds the whole toolset. Switch tools with the number keys, pick from a 12-color palette and three stroke weights, and undo or redo anything.
Boards live as plain, versioned .wbj files on the device with a PNG preview tile next to them. Browse by thumbnail, search by title, and reorder by name or last edit.
Everything you need for a quick sketch or a full planning session — and nothing you don't.
Pinch to zoom from 0.2× to 8×, drag to pan, and fit any board to the window in one tap.
Turn the background grid on or off to keep strokes aligned or stay clean.
Every change is a reversible command. Walk back and forth with confidence.
Save, rename, search and delete boards. Each is one tidy, portable file.
Render a board to a crisp PNG, or zip up all your boards and share them.
No account, no cloud, no ads. Your work stays on your headset.
There's nothing to set up. No sign-in, no onboarding, no network.
Choose pen, sticky note, shape, arrow or frame from the rail on the left.
Sketch freehand, drop notes, connect ideas, and move or select with the select tool.
It autosaves as you work. Export a PNG or share a zip whenever you're done.
Whiteboard keeps everything on the device. Boards are plain .wbj files and PNG previews stored locally; the app opens no network connection, collects nothing, and needs no permissions. See the Privacy Policy and Terms of Service.
