Juggling Lab is a free Android app developed by Jongle N7. The app is a port of the desktop application called Juggling Lab, and its primary goal is to help people learn juggling patterns and create new ones. With Juggling Lab, users can animate all solo and passing siteswap patterns, including synchronous and multiplexed patterns, and patterns involving movement of the juggler bodies. The app also supports bounced throws, including multiple bounces and hyperlift/hyperforce throws.

The hand model in Juggling Lab is realistic, with cubic spline hand paths that match the velocities of balls at throwing points. Integrated siteswap pattern generator and a step-by-step list of basic tricks to train yourself in order to master a more complex trick are some of the other helpful features of the app. The app has a huge (400+) categorized list of tricks, including JuggleMaster's, and users can bookmark their favorite tricks. Additionally, the app allows users to pinch to zoom, rotate, pause and change the speed of the animation. Users can also add, delete, and rename pattern lists and tricks, and share tricks with their friends.

Overall, Juggling Lab is a comprehensive app for juggling enthusiasts that offers a wide range of features to help them learn and create new juggling patterns.
