Great. And free!

Those of you silly folks who gave this app one or two stars need to google how decibels work and what sounds are measured at. For instance a whisper is 30 db. Normal conversation is around 60 to 80 db. Sounds shouldnt be more than 85db to protect your hearing. This app runs pretty close to accurate. Its gets five stars from me because its free and looks nice! Worth the space on your device.
