The thought of being watched (and, therefore, controlled) by other people scares most of us. However, not everybody knows how to fight this kind of thing. Well, it’s not hard, you don’t even need to write code or understand how the Internet security should work.

  • See the history of your camera/micro usage. The app collects statistics on that so you can easily get a graph reflecting the time when your camera or microphone was used (it doesn’t matter if it was you or not; the app just reflects the usage). 
  • Create a widget to place it on your home screen and get fast access to the micro or camera.
