  1. 3/5The 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.

  2. 5/5Band Teacher

    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?

  3. 5/5It is great and has helped me but….

    I like this app so much and it helps me with pitch althoughI do wish the user could determine the range the pitch is in, Personally I wish I could choose the range of the bass guitar.

  4. 5/5TERRIFIC for ANY MUSICIAN!

    I’ve pretty much had this app since early 2020, and I’ve loved it ever since. I really love the additions that this app has added on especially the rhythm games, new pitch games, tuner, metronome, etc. I REALLY love this app and I can’t wait to see what can be furthermore done with this app and its possibilities.

  5. 4/5Would 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.

    Three new stages are here! Scale Guess Name the notes of a flowing single-line melody by ear, do-re-mi style.

    You can now change the app icon! From Settings, pick any of six character icons — Ebifurya, Kakifurya, Murugai, Takoyaki, and two Unicchi designs. They are all free. We also refreshed the default icon with a new Ebifurya design. The characters got a visual upgrade too: brighter eyes, and a glossier look for Unicchi. We also redesigned the ad-removal and purchase screens for clarity, gave the weekly ranking a new look, and fixed several minor issues. Thanks for using Harmonize!

    See the role of every note Double Stop, Moon and Low Register now show what each sounding note does in the chord — root, third, fifth and so on.

    The tutorial got a complete makeover! Kakifurya now appears in person, chatting through speech bubbles as she teaches you how to play. New hints kick in when you get stuck, so first-timers can find the knack of pitch-matching much faster. In the Chords stage, badges now show each note's role in the chord (root, 3rd, 5th, 7th), so you can practice while learning what shapes the harmony. More improvements: - Volume sliders now respond the way your ears expect - The status bar (clock and battery) is now visible - Better takoyaki board layout on iPad - Minor bug fixes Thanks for using Harmonize!
