The app functions on YouTube only, so you will only be able to use LookAway Player's features on YouTube videos. In my testing it worked pretty much as advertised. Simply play a YouTube video, and when you turn your head to look away, facial-recognition software automatically pauses the video. When you turn back toward your iPhone, the video starts up again. It also worked when I looked down, but had trouble when I was looking upward. When I just turned my head away from my iPhone, the feature worked pretty well. You have an option in the settings to turn off what the app calls Vision Control, but if you're going to turn off the main feature, you might as well use a more feature-rich YouTube client.
The Good LookAway Player gives you Smart Pause-like control of video on your iPhone before the feature is released on Samsung phones.
The Bad While the look-away feature works pretty well, LookAway Player's muting feature is less than satisfactory. It's also very limited as a YouTube browsing tool.
The Bottom Line LookAway Player's main feature works as advertised, but the muting features and limited YouTube browsing tools make it essentially a one-trick pony.
