WizzJ is a cutting-edge music visualizer for high-end iOS devices. It fully exploits the latest advances in graphic processors to create a flow of animated generative art.

WizzJ represents a new generation in the art of music visualization! Download WizzJ for free and enjoy a fully functional preview of the available 36 styles, each providing a unique and immersive experience: A Flower of Life, Alien Speak, Ancient Glyphs, Beat Tunnel, Beat'n Chaos, Blossoming, Breeze of Oil, Brick Islands, Color Wand, Cricumpunct, Crystal's World, Dancing Blobs, Disco Sun, Entwined, Girl's Best Friend, Holes of Color, LP's Revenge, Matrix, Neon Ice, Ocean, OneHundredEiiigghtyyyy, Phoenix, Polar Texture, Pop Art Dive, Puzzled, Rainbow's Birth, Sandworms, SpeedBeat, T-Rex's Skin, Tentacles, The Beauty Within, Threads of Light, Threesome, Wanna Kiss?, Wave Dance, Wheel of Color. WizzJ uses Apple's built-in media player and can thus access your existing songs and playlists. In contrast to most other visualizers, WizzJ analyzes the sound of played songs without using the microphone; hence you can enjoy WizzJ even with headsets. Note: Apple does not allow to analyze streamed music. Thus, only music saved on your device and played through the internal iOS audio player is supported. Unfortunately, Apple Music, Spotify et al can therefore not be supported. WizzJ can support the device's native display resolution for a detailed and crystal clear presentation. Activate this feature in the Settings App if you have a powerful device. You can easily create your own music videos by capturing WizzJ's animations with QuickTime and your Mac. Videos and more info can be found on the "Developer Website". Customer comments: ***** Unbelievable Music App "Best music app so far in iTunes Store.
