★★★★★

Myron Green

A visual problem solver between apartment neighbors, this app is proving to be. I'm impressed and pleased to have it so readily available.

★★★★

Supa Loki

Nice. Easy to use. UI is clean and effective. No ads on 2.0. For calibration, set to -12 on s9 and -9 on N20U. if unable to capture loud noises, that's due to mic limits. The app is limited by the values generated by your phone's microphone. Also, app uses front mic nearest to you (next to usb-c port). cannot set mic.
