Flawed implementation sullies viewing the great images. All "Latest Images" should download automatically in the background at launch. Instead, one must wait for each to download individually as one clicks through the list.
Similarly, upon installing, each category should download in the background upon first invocation. Could at least download enough to fill a buffer, to kill the long waits.
The pictures are exciting, but the app is no fun to use. I deleted it.
