Tone Generator Ultra

The app worked but I didn't find like the user interface. Changing frequencies was a pain. The slider was linear instead of logarithmic, making it impractical since the most useful frequencies are crammed together in a small part of the slider. I'm resuming my search for a useful tone generator.

Could not get it to generate ANY sound. Waste of time, and money. Would give negative stars if I could.

This app is worthless because it stops playing sound when you switch away from it, even with the "Keep Alive" setting enabled in the app. How am I supposed to switch to my RTA app to analyze the results of piping the tones through my PA if this app stops making sound when I switch away from it?!?

Very useful for Car audio, Guitar tuning... Has many useful tests

It works as advertised, but I wanted to use it to test the frequency output of my Bluetooth speakers so I could use that as a guide for my equalizer settings. But the output only goes to the tiny iPhone speaker, not out to the Bluetooth device.

You can make all fundamental sound such as sine waves, noises, octave and finding note frequency. If it has harmony function, it'll be the best app of tone generator.

I couldnt get any sound to play.

The UI is good but the sound ends up distorted, and it stops playing while it pops up ads.

This is the perfect tool for calibrating my home theater! It does need to fix the airplay function. Just not work

Love this app. More so when equip with A2DP for BlueTooth connection, as an alternative to hard wiring.
