Boom Catcher listens for screaming exhausts. When they bust the dB limit, your phone catches it on video so you have the receipts.
Could be your current phone or an old one in the drawer? Plug it in, position it, tap ARM. Boom Catcher captures the noise.
Modified exhaust hits 88 dB. Boom Catcher auto-captures a short clip with the offender centered in frame.

Most US states set pass-by vehicle noise limits between 80 and 95 dB. Modified exhausts routinely crack 100. Boom Catcher logs the exact number — so the conversation stops being "it's loud" and starts being evidence.
Decibels are logarithmic. That means every +10 dB is 10× the acoustic energy — and sounds roughly twice as loud to your ear.
A single modified exhaust at 100 dB drowns out ten thousand conversations at 60. "It's just one guy" isn't just one guy.
