3D Films Preview is an Android application developed by Alex L. Reigal, available for free in the Lifestyle category. The app allows users to watch 3D movie previews on their smartphones with Virtual Reality glasses. The program offers the option to choose between SD or Full HD, depending on the user's screen resolution and bandwidth. The higher the phone screen resolution, the better the results, especially with Full HD and bigger screens. The app also provides subtitles in English, Spanish, French, Russian, and Chinese.

It is essential to note that the software only offers previews of 3D movies and aims to provide users with a true 3D experience. The developers have designed the program to resize the original 3D video files, allowing for optimal viewing with a mobile and VR glasses. The application is experimental and for developmental purposes only. The developers do not intend to interfere with the conventional home 3D market or any theatrical 3D market and their profits. On the contrary, they promote these markets by giving new users access to a 3D experience. The developers' goal is to demonstrate that the Media Industry could attain access to a new global market through this new distribution channel, offering 3D technology a real second chance.
