Funny someone can pick up the sound of a subwoofer from this app yet I can’t pick up the construction going on all around me. I can feel the pounding my house but this barely picked it up.

Are used to measure vibration

I was either losing my mind, or my walls and floor were vibrating for hours at a time from my new neighbor listening to house music at all hours. This app actually allowed me to track the 1.6 earthquake-like vibration coming from their subwoofer and gave me the information needed to help put a stop to it, and regain my sanity. Thank you!
