Pretty accurate and free!

This app seems to be pretty accurate. I compared it with my Radio Shack meter and it reads within a few db. Only change I would like to see is a digital readout in addition to the analog one. I think a lot of the negative reviews are from people that dont understand how sol meters work... Even in a room you think is "silent" a meter will still read 30-40db...thats just the way it is...
