Develop a 360-3D-Video Application

We are looking for a freelancer to help us with our project. We need a 360-3D-Video Application that runs on IOS and Samsung Android. The video should have a graphical userinterface where the user can select a video - then the video should start to playback the videos either in 360-3D-mode (2 different eyes) or 360-2D-mode. To get an idea what its about look at the App "Within" - this is somehow what it is supposed to look like. The App should be developed in a way that we are able to change the content later on to update our new videos into the Application.
