“Want to improve your pitch?” “Want to sing more in tune?” Harmonize is an ear-training app designed for people who want to develop a better sense of pitch. In Harmonize, you listen to basic intervals and harmonies such as octaves, perfect fifths, and major thirds, then try to recreate the same sound. It’s a fun way to check whether you can correctly imagine pitch in your mind before practicing singing or playing an instrument. No music theory knowledge is required. A cute character, “Ebifurya,” guides you with the correct pitch, so you can naturally train your ear by listening and matching the sound. The app uses just intonation harmonies. By becoming familiar with pure harmony, you can learn to notice even small pitch differences more accurately. This can help you sing or play more in tune in karaoke, choir, brass band, orchestra, and ensemble settings. It is also recommended for developing relative pitch. Harmonize is used by vocalists as well as people who enjoy brass band and orchestral music. Download it for free and start training your ear while having fun.

Would be perfect with some more options :)

I’d like the ability to choose different waveform types for the sound, or mix and match them (one note with a sine wave and another square, for example). It would be great to have more of everything, too!But this is fun.

The UI feedback is really clunky

The sliders on the left and right provide no visual feedback if they are being changed, and their parameters extend beyond the screen. So at times it’s hard to tell if you’re actually successful in adjusting the tone. Having the slider be a wheel, (visualize a mouse middle click wheel) would be a better system. The left slider seems to go behind the pause button, it’s hard to tell where the sliders actually end on the screen. If you want to continue raising the tone once you hit the top of the screen, the game instructs you to start at the bottom again. It’s not clear if that’s the same case for continuing to lower the tone after you touch the bottom of the screen, since the pause button is there. Does it work this way only if you start at the edges, or can you change the upper/lower limits of the slider if you start closer to the center? The UI doesn’t make that clear, and the fact that it’s a text box telling you to start at the bottom again is already an example of bad UI. There are also ads after every screen, but those can be turned off for a single $9.99 purchase. It’s a neat game, but the instructions and interface are way to too awkward.

This Game Is Great

I really love this app, and it challenges me in a fun way, one that pushes me further and encourages my ears and spirit. I am fluent in the world of music, and play both trombone and percussion instruments. Our Band director encouraged us today to get this app, and it is great that it is free and so fun to use!! I recommend this app to anyone who wants to go farther in the impressive world of music.

Crashing a lot in 2025. Great app for teaching/hearing intonation.Suggestion- 1. A way to set parameter of tones (most of the examples I listened to would be too high for students to discern) More low note intervals please! 2. Different voices that more closely resemble an instrument rather than a sine wave. 3. Ad-free version with paid upgrade. I'd pay $1-3 for the app if it had some of those tweaks. Dislike- sometimes I get three stars for being +/- 5 cents whereas other examples its on two stars. What are the guidelines for scoring?
