Ratings and reviews

I installed and then had to uninstall this app. Once opened, you can't exit the app. Once opened, all the usual Android buttons and menus disappeared. I tried the usual things to exit the app. The thing that finally worked was Android's "pull-down" system menu accessed by swiping down from the very top of the screen. It was the only piece of Android's UI still accessible.

It's ok to get a ballpark, ads & popups are a little annoying, but functional to determine how loud outside hangs are. (compared to an AC unit, ya know? ) Comparison notes are helpful & super relatable. "Real time charting" is nice to kind of pick out what is what, but overall use the app sparingly to cut down on resources, and passive listening. I feel neutral, but it works. 4 stars. Tell my family, "hello".

It picks up the low frequencies i am hearing. It says its a clock ticking, but there is no clock in the house. It is picking up a deep low sound hitting the walls of the house. No one else can hear it but me. It is very loud to me. This app lets me show people the vibration i hear and feel. Awesome app. Wish it could correctly identify the sound though
