Deep Galaxies HD Free is a personalization application developed by Mozg Labs. It is a wallpaper that allows you to travel to distant and unreachable worlds through your Android device. The wallpaper has two scenes: Spherical and "Fly Through" nebulas, and two unique color themes: Fire and Ice. It also offers three background themes: Stars, Deep Blue, and Deep Red. The wallpaper is enhanced with space dust, and lots of camera settings are available, from sensitivity to distance. The program is optimized for performance, running on 100% C++.

The full version offers more features, including seven different shapes like Spherical, Flat, and Evaporating nebulas, Quasar, Hand of God, and Spiral Galaxy. It also has ten unique color themes, nine unique background types, and three different density options. The wallpaper has both gyroscope and free cameras, and tons of camera settings are available, from sensitivity to distance. The visual experience is enhanced with OpenGL ES 2.0, and the FPS can be limited to save battery. It is worth noting that if your phone does not have a gyroscope, you can still use the free camera mode and control the camera with your fingers. This is the first release, and more updates with new themes, shapes, and preferences are coming soon.
