This is a good app in general. It does the job it was designed for. I installed it because I wanted a way to put my phone on mute once shaked. I uninstalled it because the app reset the volume levels to different volume settings once it's shaked again to unmute. Not convenient.
Seems to be working perfectly; hope it keeps it up.
