Magnetic Balls Free is an interactive personalization app developed by Adermark Media for Android devices. It features magnetic balls that react to touch and allows users to customize the behavior of the balls.

One of the key features of the app is the ability to select a photo from the gallery and have the balls shift color to match the image. In addition, users can choose from predefined presets, custom ball and background colors, and even enable random color changes when touched. The app also offers a parallax mode, color bleed to surrounding balls, reverse lift, lift speed, gravity, amount of bounce, and float time before dropping. Users can also choose from a variety of object shapes, including ball, pyramid, square, cross-stitch, token, fuzz, star, dollar sign, and at sign. The app offers a customizable grid distance, distance between balls, ball size, and lift neighbors.

While the free version of the app has most of the settings locked, the full version offers a plethora of customization options. Double tapping the screen resets the color of all balls back to the original color or photo. Magnetic Balls Free is a fun and interactive app that offers a unique personalization experience.
