There are apps to let your phone do both or more reasonable would be to set up a security camera to record your backyard or something innocuous, use it to file a report and if nothing happens from the police report take it to the city council to show they aren’t enforcing city ordinances. I’ve seen a few people take noise complaints to council to get it enforced.
I wish there was I could do that. But what am I supposed to do? Stand on the corner of a street with my phone out and a DB meter in hand?
