Shi - monitor your noise

A while ago when I used to live in a share house, I needed something to alert me when I was speaking too loud to don't wake up my friends. I couldn't find on the web so I made this simple app. Choose the sensibility, leave in the corner of your bedroom and will turn on the screen once you start to speak too loud.
For me has been very useful so I'm sharing with you in case you are looking for the same thing. Just please, don't expect too much from the App because its very simple.
