Tone Generator Ultra App Reviews

As a retired Broadcast Engineer, I can use this app along with my iPhone 5 as an audio frequency generator. With the appropriate audio cable plugged into my phone, I can do a freq run into my audio console (mixing board). The app is very handy & convenient!

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

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

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.

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

If it wasn't because of the constant ads this would be a great app.

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.

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?!?

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.
