    Fair to poor. Very frustrating this app will turn your volume all the way up can blow speakers be careful. Also needs ability to run in the background.

    This app when you turn it on has the vol on max every time. This app should be marked as a health hazard. Too bad though, once you regain your hearing and turn it down the pink noise is very smooth. Uninstalled not worth it

    These graphs leave little wiggle room for low freq ones. Mayybe only 1/10th of the slider scroll is dedicated here. Above 2khz, is okay. Below it, u have to type the desired freq, if u likt to play below 2khz,a lot, u will have a devil pf time tweaking as there is little scroll range dedicated here,go elsebwhrre

    1: Upon starting, my phone asks if I am sure I want to crank the earphone volume up to 100%, indicating that some app tried to do so. 2: It stops when the screen goes to sleep (after 30 seconds in my phone) making it useless for ambient sound continuous blocking.
