### 4/5 — 役に立った

*2026-07-16*

吹奏楽部で音程がわからなかったけどよくわかるようになった！もし出来たら、あえてユニゾンの音で音程が微妙にズレてて、これは高いか低いかっていうのを答えるっていう形式も出たらいいな思う

**Developer response:** 吹奏楽で音程が分かるようになったとのこと、とてもうれしいです。ユニゾンのわずかなズレを「高いか低いか」で聴き分ける——耳を鍛えるのにぴったりな遊び方ですね。教えてくださってありがとうございます。前向きに検討させていただきますね。

### 3/5 — 楽しいけど

*2026-02-03*

和音の問題を始めたらオクターブに戻れなくて困ってます。
復習したいのに、、

### 3/5 — 広告が多すぎる、音が高め

*2024-10-29*

30秒くらいのゲームをクリアするたびに30秒ほどの広告が流れます。煩わしさこの上ないです。こんなに煩わしいならいっそ有料にして欲しいです。
あと、扱う音が高いです。低音も練習したいです。

### 4/5 — Pretty good

*2024-08-13*

Helps me wth violen tuning but can get a little annoying if the pitch gets too high

### 3/5 — The UI feedback is really clunky

*2024-03-19*

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.

### 3/5 — 広告が多い

*2024-02-11*

一問毎に毎回広告でやる気を削がれる。特にロイヤルマッチとチョコザップはひどくしつこくて、最低。

### 4/5 — Fun app for just intonation training

*2024-02-09, version 4.1.11*

I used this to grok in my minor thirds and minor sixths by ear.

App developers - could you allow custom intervals, I want to train the minor second 10/9 as well as some of the septimal intervals 7/6.

### 4/5 — Terrific for ear training!

*2023-11-08*

I like this game a LOT for ear training. I’m not overly fond of the default tone, but I’m glad I can switch it to piano or violin, so it has a more pleasant timbre. Also, I like that it shows the frequency of the sound. While not the same as other people’s measurements for perfect pitch, it’s pretty close, by hertz. 

My only complaint is that, I wish it was possible to turn off the applause and whistling that automatically plays when you win a level. The whistling person sound in particular can be very shrill and ear piercing if you had to turn up the volume to better hear chords and fifths and other sounds that are in lower, bass clef notes. 

It can be a little difficult to get the sliders to go where you’re trying to get them if you’re a visual person as well as auditory, however, you get used to it and just focus more on the sound than how far it “looks” like it’s going to move in pitch. That helps. 

Other than that, I enjoy this game a lot and think it’s terrific for ear training!

**Developer response:** Thank you very much for your feedback. We are currently applying for a new version that includes a feuture to reduce sound effects. Please look forward to new releases.

### 3/5 — 設定が少ない

*2022-12-27*

たとえば、もう少し厳しめにすることができるようにしてほしい。

**Developer response:** 評価いただきありがとうございます！貴重なご意見、今後の開発の参考とさせてください。

### 4/5 — 移動ド唱法を勉強してから

*2022-08-22*

移動ド唱法を勉強してからやるとためになると思います。
用語の知識がなくても大丈夫、みたいなことを書いてありますが、移動ドや使われている用語の意味を知らない時点で使ってもあまり意味がないのでは？

**Developer response:** 評価いただきありがとうございます！貴重なご意見、今後の開発の参考とさせてください。

### 3/5 — Too many ads

*2022-02-15, version 4.1.7*

Decent app. I understand it’s free and ads are to be expected, but the ads on this are out of control. Every time you click anywhere, even to look through levels; another ad, and they’re so repetitive

### 5/5 — 很用心

*2021-07-20, version 4.1.6*

期待作者能持續更新增加其他和弦與小數點後的精準度等等，這個app在訓練樂團合唱團等音樂領域的工作者非常的受用，真的感謝很感謝開發者！

### 4/5 — 好きですが出題ミスが

*2021-07-02, version 4.1.6*

耳を鍛えるのにとても使いやすく感じております。「長三和音」の問題として短三和音が鳴らされるなど、一部出題ミスがあるようです

### 5/5 — 初めてのレビュー

*2021-04-18, version 4.1.4*

レビューをすることは基本的にないがこのアプリだけはすごく良かった
わがままをもうちょっと色んなモード(例えばメロディの音がなんセミトーン離れていたか当てるクイズ的なの)とか音のクオリティや
ランダム楽器(全ての音ごとに様々な楽器がランダムで付けれられる的な)機能が欲しいと思った

### 2/5 — 広告表示後いつまで待ってもゲームに戻れない

*2021-01-31, version 4.1.4*

iPadでやってるんですが、エンパイアーパズルという広告が表示されると、クリアしても、アプリページへとんでも広告が消えず、アプリに戻れません。他の広告は平気何ですが…

### 5/5 — Great for string students

*2020-12-03*

I use this excellent game to train my violin and viola students to hear and match pitch well. Students of all ages have found it to be fun, challenging and helpful. Thank you for creating this game!

### 1/5 — Ad after every use

*2025-12-03*

Purchased no ads on my family account but STILL see an ad after every use…horrible

### 1/5 — Unusable

*2024-10-29*

App is unusable because of aggressive ads and lack of instructions about how anything works. I clicked on the perfect fifths thing, pressed the go button and it instantly said i failed and made me watch an add.

Really just an annoying app that could probably be good if the dev found a way to monetize it without aggressive ads and made it more obvious how to use it

### 1/5 — More ads than any app I've ever used

*2024-07-10*

Every time I click on any button on this app, there is a 3/4 chance of a long, unskippable ad being played. Just about unusable.

### 1/5 — よわw

*2024-01-06*

よわw

### 1/5 — 操作方法不明

*2020-08-11, version 4.1.4*

説明もないから意味わからない

### 1/5 — 意味わからん

*2020-05-07, version 4.1.3*

使い方がわからん。使い方をYouTubeでみて、同じようにしてみたけど音が高くなったりしないし、頭おかしいアプリ

### 1/5 — What happened to the note names?

*2019-12-17*

The previous version had which note one was aiming for - why is this no longer available?

Updated in 2019: still no note names. Please allow this as an option!

**Developer response:** Thank you for your feedback. We added note names on version 3.8.1 or later. Please update and try. Thank you.

### 1/5 — は？

*2019-11-24, version 3.7.1*

なにをするのかがわからんし、
何をいえばいいのかもわからん

### 1/5 — めちゃくちゃノイズが入る

*2019-09-03, version 3.7.0*

はじめて少しするとブツブツノイズが入る
まともにプレイできたものではない

### 1/5 — わかり辛すぎる

*2019-06-22, version 3.6.4*

わざわざ説明用のページなんて無くてもわかるくらいシンプルにしてくれ。

### 5/5 — 和音のステージ

*2026-07-31*

バージョンアップで単音が鳴るようになりましたが、以前のように和音だけが鳴るような設定はないでしょうか。

**Developer response:** ご意見ありがとうございます。分かりにくくなってしまい申し訳ありません。

お手本ボタン（緑）を押したときは、以前と同じように和音がそのまま鳴るように直しました。
問題が始まるときの自動再生は、構成音を1音ずつ聴いてから重ねる形のままにしています。

この変更はまだ配信前で、次のアップデートに入ります。
今しばらくお待ちください。

### 5/5 — TERRIFIC for ANY MUSICIAN!

*2026-07-27*

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.

**Developer response:** Thank you for sticking with Harmonize since 2020 — that means a lot.

We're still building: the next update brings a new practice stage and a number of
refinements to the existing ones. It hasn't shipped yet, so please give it a little time.

If there's something you'd like to see in Harmonize, we'd love to hear it.

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

*2026-07-17*

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.

**Developer response:** Thank you so much — it means a lot that Harmonize has been helping you. And what a wonderful idea. Choosing your own range to practice in, like the bass guitar’s, is exactly the kind of thing that would make this ear training richer. I’d love to look into adding it. Thank you for sharing it.

### 5/5 — 楽しくてためになる

*2026-07-17*

音を上下させて、調和させるときの、濁りがだんだんと透き通っていくような感じが好きです。アンサンブルのための音程取りのトレーニングにもぴったりです。

**Developer response:** うれしいご感想をありがとうございます。濁りが少しずつ澄んでいく、あの瞬間を楽しんでいただけて何よりです。アンサンブルの音程取りにも、ぜひ使ってみてください。

### 5/5 — 最高

*2025-07-23*

音感を鍛えるアプリ求めてたので本当に助かります！

### 5/5 — Band Teacher

*2025-04-04*

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?

### 5/5 — 星5

*2025-01-20*

これをすると段々オクターブの違いが分かって来た

### 5/5 — 良い

*2024-04-19*

素晴らしい

### 5/5 — Sus4追加して欲しいなぁ

*2023-04-26*

すごい神アプリですね！やってて楽しいです。 一つだけ要望があって、和音にsus4（あわよくばsus2も）があると嬉しいです。 自分はアカペラをよくしてますがsus4はメジャーの次に頻繁に使われるものなので…！

**Developer response:** 高評価いただきありがとうございます！sus4の件、今後の開発の参考とさせてください。

### 5/5 — LOVE it!!!

*2022-04-16, version 4.1.7*

I love this app, so useful and CUTE!
