No Info – Sonic Pitch Sound Generator Review

As I am not a frequency educated person, I have no idea what frequencies to use for repelling dogs, rude people, etc. There is no list or chart to inform, at least none that I could find. The only indicator is a representation of a mosquito and a water droplet. Touching or swiping screen or icons did not give further information. At least I did not pay for this app.
