After you see an Alfa Romeo C43 Formula 1 car in your living room, you’ll have no doubt: JigSpace is no ordinary demonstration app.

What we love: For hardware reviews and model walkthroughs, JigSpace’s spatial presentations feel like you’re summoning a product out of thin air. Pull apart a model to take a closer look at a specific section, or follow an interactive path to see how things really work.

Don’t miss: All the preloaded sample projects. In addition to the Alfa Romeo and anatomically accurate heart, see NASA’s New Horizons space probe, a working jet turbine, and more. These are more than just demonstrations: They’re inspiration into just how real your objects can look in your audience’s space.

Quick tip: To annotate a model, pinch and draw in the air—just like you’re holding a pencil.
