It is in fact a great app that does what it says. I use for streaming movies from my NAS to apple tv without turning my pc on. I discovered some other apps that can do the same but this one is very simple in use and pretty stable.
However, what i discovered with the last update is that it drains the battery extremely fast in some instances. Moreover, a few times when i played videos on iphone without airplaying on apple tv it heated up my iphone in just couple of minutes so that i could feel the heat even through the case which is pretty thick in fact. I suggest this issue is addressed asap.
Dont know about the music skips others reported about simply because I dont use it for music. Videos play fine.
What I would also prefer to see this app doing is to have the ability to search for a new video or music on NAS after playing a file without stopping it, the same way YouTube does (minimize video by sliding it down and search for something new while it is still playing). Now when you play a file and want to look for another file you can only do that by stopping the first one. Dont know how difficult it is to introduce this feature but it is also relatively not a cheap app so it would be worth having it, for the money.
