hearEQ builds your EQ skills to professional levels using custom ear training exercises, created just for you from your favorite songs. Simple, powerful, and fast, hearEQ is perfect for ear training on the go. Named one of "The best iPhone and iPad apps for musicians" (www.apppicker.com), here's what the experts have to say about hearEQ:

"When I found hearEQ, I knew this was a game-changer. From the ease of use and the ability to use your own music selections, hearEQ is perfectly designed to be the go-to choice for developing your ear. My students have shown tremendous improvements in mixing and productions, and I completely attribute this to hearEQ. Thanks Ten Kettles! Keep up the great work. You are making a difference!" -Chandler Bridges, Ph.D., Professor (The Los Angeles Film School); Audio engineer (Will Smith, Aaliyah, Johnny Mathis, P-Diddy, J-Lo, Bette Midler, LeAnn Rimes, and more) with two Grammy-winning albums.

“After half an hour with the app I had a noticeable improvement to my score, but I was also thinking in much clearer terms too!” -Tim Webb, www.discchord.com

“This handy app is one of the greatest tools I've seen for helping you hear exactly how EQ adjustments affect your sound. Wish I would have had this when I was first learning how to mix live sound.” -James Wasem, www.greatchurchsound.com

"hearEQ…makes the experience of ear training enjoyable enough to seem like fun. [It's] a great educational tool." -Tom Flint, Sound on Sound: The World's Best Recording Technology Magazine

“The principle behind hearEQ is beautifully straightforward…even with a little repetition, things do start to improve and I suspect if you were to build some hearEQ into your daily musical routine, you would soon reap some positive benefits.” -John Walden, www.musicappblog.com


Every frequency range has a color, a quality, a character. For sound engineers, musicians, and other enthusiasts, knowing how to apply this to an equalizer (EQ) can make a transformational change to your sound—whether you're mixing a live concert, a recording, or even playing music through iTunes. (VIDEO @ www.hearEQ.com)

It's a simple app with a powerful promise: if you learn the qualities of each frequency band—for example, cutting 4kHz puts sound in the background—then you can make equalization work for you, and truly transform your sound into something professional and beautiful.

hearEQ uses your favorite songs on your device to create custom ear training exercises that a) teach you all about frequency bands, and b) help you really hone your EQ skills. A standard 10-band or 30-band* equalizer is used, just like you'd find in iTunes and on many professional sound mixers. Your song will be played back with a simple equalization applied—and you guess what it was!

> Was it really clear, maybe a bit hollow? Could be a 1000 Hz cut.

> Was it muddy? Maybe that's a 500 Hz boost.

> Was it really present, almost too in-your-face? Sounds like a 4kHz boost.

Ten questions, ten frequencies, and then you get a score. Want to focus on just a few frequency bands to start? You can do that too. Keep at it, and you'll be an EQ master in no time.

*The 30-band equalizer is part of the "Advanced EQ" module, available as an in-app purchase within hearEQ.

NOTE: hearEQ works with any track on your device, with the exception of tracks that prevent our EQ processing, such as DRM-protected tracks and cloud tracks (e.g., Apple Music). That said, hearEQ ships with several built-in practice tracks, so you'll be able to start EQing right away!

Absolute Lifesaver

This app is awesome– it’s the only one I’ve seen that quizzes you on boosts AND cuts and it’s so easy to use your own music. It’s best if you don’t use phone speakers, I do it in my car and with headphones. It’s super fun and easy to do for a long time. My ear has noticeably improved. The price is insanely worth it if you’re dedicated to improving your mixes. This is a company that obviously cares for musicians– hearEQ, beat mirror, and Waay are all such valuable tools for improving your ear and musicianship. Genuinely, thank you!!

Just too expensive for what you get

I really liked it at first but for paying $6 the advanced eq and pink noise should all be included and it sorta ticked me off that it wasn’t to be honest. I mean the entire gta game on mobile is worth that much and I could load any song into fl studio and pull up the eq and test myself that way for free. Despite that I would still actually use the app because it is well made but it just doesn’t feel worth it unless it was all included and now I sorta just feel urged to use it just to get my money’s worth out of it. No disrespect to the creator because you did do a good job making the app and I guess I shouldve looked into it more before buying it anyways but for $5.99 there shouldn’t be any micro or side transactions whatsoever that is a big enough price to include it all in one package and without that it just feels like $1.99 app at most

Not sure why but every time I try to open the app it immediately crashes/closes making it unusable. I uninstalled/reinstalled it several times with no luck. iOS version is up to date etc... Please fix?

UPDATE: the app finally opens and functions fine now, i thought it was due to an updated version since my last review but since the Dev responded and i dont see any changes in the Version History timeline i'm not sure what happened; but i'm glad i can finally use the app! Gave it 4 stars for the nice interface and good customer service, will update my rating again once i experience the app's learning results and methods etc.

Developer Response ,

Hey, thanks for getting in touch. Sorry to hear about the crashing; that definitely sounds frustrating! I haven't heard of this happening before, but let's get to the bottom of it. Can you email me at alex[at]tenkettles[dot]com with some more information (device type; when the issue started happening; whether you're using the device speaker, wired headphones, bluetooth headphones, etc.)? Thanks and talk shortly, -Alex
