Questions, answered.

Is it free?

Yes, it is free to download and you can build real projects for free. Pro adds unlimited projects and unlimited video layers, available monthly, annually, or as a one-time lifetime purchase.

Do I need a laptop or special software?

No. You design everything on your iPhone, iPad, or Mac, then connect a projector directly over USB-C or HDMI.

What if I don’t own a projector yet?

Design your whole scene and preview it in AR on your wall today. When you are ready, any USB-C or HDMI projector works.

Can it handle curved surfaces?

Yes. Mesh warping wraps content over columns, arches, and rounded surfaces, and you can stack multiple surfaces and layers for a full mapped scene.

Is it safe for flashing effects?

Some effects, like strobe, use rapid flashing light that may affect people with photosensitive epilepsy. Please use those effects with care.
