Sonic Frequency Toolbox for iOS

With the "Sonic frequency generator", you can easily generate sound from 1Hz - 30kHz, and different frequencies of sound and noise can be used in different scenes.

It can also be used as a small collection of sonic tools in life, such as pranks to annoy friends, dog whistle training and anti-mosquito etc.

More sonic gadgets are available for you to discover.

Of course we also provide a decibel meter, you can use it to measure the noise level of the surrounding environment at anywhere.

Hopefully, anyone who needs something to do with sonic frequency can find what they need from here.
