MountainView doesn't provide much as an app, but if you are a photography buff and enjoy images of mountains like those from the Valley of Ridanna, it will serve you well. Composed of numerous photographs taken in the Valley of Ridanna and a fairly easy-to-navigate interface for viewing those photos, MountainView is a fun app for those that enjoy the imagery of the great outdoors.
There are three screens in MountainView -- the home screen, the gallery screen, and an About page. Swipe your finger to the right and they will cycle through. On the gallery screen you can move through the photos listed one at a time to see them in order. That's about all the app does; there are no tools for zooming in, sharing the photos, saving them to your device, or making notes. The images are all in black and white and when loading each page for the first time it can take a couple of seconds to display the image. So the app serves a fairly limited purpose.
If you enjoy images of mountains and don't mind the occasionally slow load times and the lack of additional features, MountainView is a fun gallery to look through. The ads at the top of the screen can take away from the experience to some degree, especially since you cannot view the images in fullscreen; but otherwise, the app works as intended and without any bugs.
