Tone & Go: Frequency Generator

AndGo Apps

About this app

Just type in any frequency and play it on your mobile. It is useful for music technicians, audiophiles or anyone who wants to understand how different frequencies sound.

The major musical notes are pre-configured in the app so that you don't need to know their frequencies.

The app allows you to specify any frequency between 1 and 22000Hz, more than the audible range. Please note, however, that the tone generation is dependent on your phone's software and hardware such as the speakers . Again, it is unlikely that anyone would be able to hear the full range of sounds as each individual will have their own hearing limitations.

Ratings and reviews

This is a great minimalistic app for quickly hearing specific frequencies on the go. The scrolling mechanic is too insensitive, but tapping to enter values works great. There is a note picker that lets you choose any key you want to listen to, which is perfect for my use case of testing pitch memory on a whim. There is no sweeping/sliding or option to change the waveform/sound, but for hearing and humming along to a note of your choice this app works fantastically, and with no ads!

another tone generator that has no sweep or noise functions, limited to a specific tone which is just a tiny fraction of what's offered in other similar apps. this is like the useless feature I never use when using other speaker tests.

Decent enough, but it would be nice to be able to type in the frequency, rather than having to scroll through at 1Hz increments...
