Real reviews from real users:

"Turns out, this app offers everything offered in that Berklee class of mine… in an app!"

— Damian E., No Treble

“The Quiztones app is far and away the best app I've purchased. It's an incredible tool for all audio engineers and musicians ... My mixing has improved by leaps and bounds after just a few weeks with Quiztones.”

— Austin M.

“I love this app. Has taken my ability to hear frequencies to heights I never imagined was possible at this point in my career. This app is a game changer. Be consistent with it and it will change the way you hear music.”

— JayAllDay

“This is fantastic. I’m a bit of a workaholic, and blind, audio engineer. This is like the holy grail of an iOS game for me. It’s simultaneously fun and productive. I can play on the go to have better ideas of what I’m hearing on my phone for later correction in Pro Tools, or plug into one of my monitor sets at home to test my instinct... and it’s a game, with categories and scores. Much respect.”

“Trained me up well! This app helped me become MUCH faster with EQ, and helped me know with greater precision what I'm hearing all around .”

Great app for the price

This had helped me a LOT. Not only can I determine frequency and gain changes much more easily after using it, I'm able to hear many suble differences in sound qualities that I couldn't before. The only reason I didn't give it 5 stars is because it would probably cut the time it takes to train your ears if it had an option to let the exercise keep playing until you tell it to go on to the next one. That way, you could hear the difference after you've already guessed it. That would really help to learn the differences more easily. The way it is now, it stops playing as soon as you guys correctly, so you don't get a chance to memorize how a particular change sounds. That's a pretty big oversight IMO.

Hi xaos, thank you for purchasing Quiztones! Currently the audio does continue playing for a short time after the correct answer is chosen, but we'll take a look and consider if it makes sense to extend that even further! Thanks, Dan

Great app

I would have given it five stars, if there have been an autoplay next option. This would give you the opportunity to take your eyes off the screen, so that you make your first guess from what you hear, not from what you see as available choices.

Hi rahipkil, this is a great idea. We're currently looking into adding a Settings screen for quizzes where you can customize various behaviors, including an option for 'auto-play next question'. Thank you for using Quiztones! We appreciate your support.

I don’t know what it is but I seriously could not hear the 10db boost in any of the quizzes. And I’m not crazy because I took the same piece of music and went to logic and boosted the same frequency up by 10 dB and it was an OBVIOUS boost but in the app the EQ boost was not there. If this is a bug then please fix it soon because I’m wasting my money.


I didn’t realize you had to toggle the on and off switch. You know if you could put that in as a message before the quiz started that would be great.

Hi Tony, we've added some clarification to the start screen notice about the Power button functionality. Thanks for using Quiztones! -Dan
