Great app

This app is very handy. I use this to measure how loud A particular area is to determine if it's required to wear your plugs or not so that I don't cause anymore damage to my ears; because they're bad enough already. I wish I had this when I was younger, much much younger.

Terrible app

Just downloaded this app for the hell of it, wanting to see how it worked and it stayed at 60 with no noise AT ALL. I was disappointed to say the least, especially because also, it only went up to exactly 110. All in all, it wasn't accurate and has no real use, I deleted it within less then 5 minutes, don't waste your time with this garbage!
