Ovu is a 3D drawing app. Brush ink onto floors, walls and ceilings, and a single stroke can bend from one surface to the next.
Everything below lives inside the app. Poke at the demos.
Grab the wall and drag. It snaps to the grid like it does in Ovu.
Scrub the timelapse. Ovu replays your drawing stroke by stroke.
Send a link and a friend joins your room. Their cursor draws in real time.
Portals, ghosts and a scatter brush.
Drop a doorway into one room and step through into another.
Record a session, then watch a translucent replay of how it was drawn.
Drag and plant a forest of models along your stroke.
No sign-up, no server, no payment.
Every download is free.
Ovu isn’t signed with a paid developer certificate, so your system asks for one extra confirmation.
Move Ovu to Applications, then run this once in Terminal:
xattr -cr /Applications/Ovu.app
Select More info, then Run anyway.
Make it executable, then open it:
chmod +x Ovu-*.AppImage && ./Ovu-*.AppImage
in Ubuntu 24+:
./Ovu-*.AppImage --no-sandbox
Open the .apk, then allow “Install unknown apps” for your browser or file manager.
Yes. Every download is free, with no trial and no account.
Yes. Drawing, layers, skies, history and export all work without a connection. Live collaboration and the marketplace need the optional Ovu server.
On your own device. Export a project file or a .glb whenever you want a copy.
On Android, yes — install the .apk. Touch drawing works, and exports open in your share sheet.
Store listings need paid developer accounts. Ovu is distributed directly so it can stay free.
