OpusMobile is the client interface that gives you on-the-go access to OpusOS through any number of mobile devices, including cell phones, PDAs or even fixed terminals for cars and airplanes. With an elegant and simple design for smaller screens with input mostly through touchscreens or trackballs, OpusMobile provides mobile music streaming, mobile video streaming, access to your email, contacts, calendar, pictures and more. OpusMobile is the absolutely essential mobile application for today's mobile and digital society. You keep everything in one place, but access it from anywhere.

Two versions of OpusMobile are available, one in J2ME and one in Flash Lite, which allows it to run on most modern phones including Nokia, Motorola, Samsung, LG, Android phones, Windows Mobile phones, iPhones and Blackberry phones. Additionally, ViaCube is currently working to modify OpusMobile for a WiMax connected car prototype, which will give you access to your digital life right from the dashboard of your car.

In keeping with the vision of cloud computing, all data, including emails, photos, contacts, music and videos are streamed on demand to OpusMobile. No actual data reside on the device, so there is no need to sync at any time.

OpusMobile can be branded and customized to suit a partner's needs.
