The GraviTrax app is a mobile and tablet application that allows users to design and simulate their own interactive ball tracks. It uses a free editor to build custom tracks and then lets you experience them roll with the balls from various camera angles.
Key features include a free track editor for building custom designs, interactive ball rolling simulations, multiple camera angles for viewing, the ability to share track designs with friends, and gameplay based on physics principles like gravity, magnetism, and kinetics.
The app itself is free to download and use, featuring a free editor for building tracks. However, the description mentions that starter kits and expansions for the physical GraviTrax ball track system are available for purchase, implying potential in-app purchases or related physical product tie-ins.
Common use cases include designing complex ball tracks, experimenting with physics concepts like gravity and magnetism in a fun way, sharing creative track designs with friends, and enjoying an interactive simulation of the ball rolling experience.
The app is designed for mobile and tablet devices. While specific operating system versions are not detailed, it is generally available for common smartphone and tablet platforms.
