This unofficial app, in no way endorsed by the BBC, gives you a Weeping Angel widget to put on your home screen. It does nothing. It does not move.
Not when you're looking at it, anyway.

Please note that Doctor Who and the Weeping Angels are copyright the British Broadcasting Corporation (BBC), and this app is just something I hacked together on Friday night because, hey, I was excited about Day of the Doctor coming out tomorrow.
Note that it *doesn't* use your device's camera to see if you're blinking- unfortunately that would drain your battery too fast :-(
This little novelty app is /just/ a widget - there's no launcher icon! You need to add it your home screen just like you would any other widget - depending on what device you use, the way to your list of available widgets is different. Try one of these ways:
* when you go to see your list of applications, is there a 'Widgets' tab? - if there is, tap it, and 'Don't Blink' should be in there.
* if you hold your finger down on an empty space in your homescreen, does the menu that comes up have until 'Widgets' entry? if so, 'Don't Blink' should be in there!
