Every piece. Every color. Infinite builds.

Klodstudio is a 3D brick studio for iPad and iPhone. Pick a piece, tap the baseplate, and it snaps onto the studs. No menus to fight, no work to lose.

Coming soon to theApp Store Free to start. One-time unlock, no subscription.

The Klodstudio editor on iPad with a red train caboose model on a baseplate, the piece tray along the bottom and the category rail on the left.

Build the way bricks build.

There is no grid to configure and no tool mode to switch. Pieces fall onto whatever is below them and lock to the studs, just like on your desk.

Pick a piece
Browse bricks, plates, slopes, round parts, windows and more from the tray, each drawn in the color you have selected.
Tap to place it
Tap the baseplate or the side of another piece. It drops into place and clicks onto the studs underneath.
Keep going
Rotate, tip it on its side, paint, duplicate or delete with one tap. Undo is always there, and every change saves itself.

Questions

Which devices does it run on?

iPad and iPhone with iOS 18 or later. It is designed for iPad first, with the same tools on iPhone.

When will it be available?

Klodstudio is in its final stretch before the App Store. This page will link to it as soon as it is out.

Is the unlock a subscription?

No. Klodstudio Complete is a single purchase that stays with your Apple Account, and with Family Sharing your family gets it too. You can restore it on a new device from Settings.

Can I open models from other building apps?

Yes, if they can save LDraw files (.ldr or .mpd). Pieces that aren’t in the Klodstudio catalog are skipped, and the app tells you how many.

Is Klodstudio made by the LEGO Group?

No. Klodstudio is an independent app by KIP Networks LLC. LEGO® is a trademark of the LEGO Group, which does not sponsor, authorize or endorse this app.
