VRphotos app for iPhone and iPad

VRphotos is an immersive viewer for 360° spherical photos. Like slide viewers of the past, it uses a carousel to store your favorite images, which are shown as spheres. You load the carousel via the sharing option of the Photos app. When you click on a sphere you are transported inside it. By default the view automatically rotates around you. When you pause the rotation the viewpoint responds to the motion of your iPhone or iPad, moving up or down, and left or right. You can also pinch to zoom or rotate the images.
Images from cameras like Ricohs Theta S are supported. The photos date and location are displayed if they are available.
