SPLnFFT Noise Meter

I’ve used this app for several years, it’s extremely accurate. I use it mainly for live music inside a club venue. This app stays reliable and steady along with upgrades of phones. I’ve found zero inconsistencies. It does help me show guitar players that their stage amp is louder than the PA.

I use this app several times a year and have used it for many years. It is a fantastic reliable and useful app. I highly recommend it.
