Customer Reviews


Went to a comedy show to see Lenny Clarke. While eating dinner, BEFORE the show started, the noise level got uncomfortably louder and louder. What started as an empty room wound up being 98 db.....Used the app and passed it around the table we were seated at. At that point everyone understood and adjacent tables were interested and impressed.
Cool, free, informative app!

Simple and accurate enough

Setting up a home studio and could not afford commercial sound level equipment. This helped me evaluate spaces and then fine fine them. Data export to find peaks was very helpful. It does not offer frequency information which would be nice.

I love it

I'm sometimes told I'm too sensitive to noise yet I am hard of hearing. Using this app has saved me from further hearing damage and brought awareness to others of their own din. Works well in public places to prove too much noise is present. Brings awareness to others too.
