After the free Lite version I had used for some time, I wanted to find out what the Plus version can do better. But since I could find little after purchase. Rather, this version has some shortcomings. So it is one of the few apps that enables any rotation when turning the Kindle. Moreover, you often have 2 - 3 times to start a connection to the cam is set up. Control of the Cam is not possible either. All this, the Lite version better. Only one display of multiple cameras simultaneously is an advantage of the Plus version. However, the tiny images that do not use the whole display by far.
So use the lite version and save the money.
Addendum: In a point I have to revise me. You can activate the camera control via a small icon at the bottom. Therefore, I now also give 3 stars (first there were 2).
