Awesome! Great for kids without headphones! Anything around/above 16500 Hz works a dream ;)

Poor low freq access range 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

WARNING: Starts at full volume! This can be a useful tool for testing your own hearing, also as a masking device which provides the common forms of white and pink noise. However one huge note of caution: do not start this device with headphones in your ears - you risk serious hearing damage! For some strange reason the app designers have encoded this so it automatically opens up with your phone set to full volume, unacceptable. I was able to use it to determine the specific frequency at which my high frequency hearing vanishes (8.4 kz)
