App Showcase: Snap ‘n Tap Lets You Drop A Virtual Marble Into Paper-Drawn Environments

Snap ‘n Tap [App Store, $2.99] lets you interact with elements drawn on paper using a virtual, physics-enabled marble. Put simply, you can draw a maze on paper, snap a photo of it, and guide a virtual marble through it from start to finish. The size of the marble can be adjusted and the app even works with lined paper.

After several minutes of playing with the app, I must say I’m impressed. It’s not developed enough to be a game, but that’s not the developer’s purpose. The ability to have virtual objects interact with hand-drawn elements is just so cool. During one test I used a piece of paper with a coffee stain on it and the ball bumped into the stain. Awesome!

The one thing buyers should be aware of is lighting. If you don’t have good lighting, the app will have trouble recognizing what is and isn’t plain white paper. I ended up having to trace my pencil lines with a pen to get everything just right. Think of Snap ‘n Tap as a physics sandbox with a twist. Perfect for anyone who wants to play with merging real objects with virtual ones.

Snap ‘n Tap is available now for $2.99 in the App Store.
