### 3/5 — Simple yet effective

*2026-06-20*

This app is a great way to learn your chords. It is simple, robust and well written, and has positive comments when you start it up. The purchase price is crazy high though.

**Developer response:** Thank you very much for your message. We are glad to hear that the app works well for you.

### 5/5 — It’s Fantastic!!!

*2025-11-07*

I’m studying theory music on the university now and this app is a great support for homework harmonic analysis. Thank you very much.

**Developer response:** Thank you very much for your message! We are glad to hear that.

### 2/5 — Pay for other keys

*2024-11-08*

The app functions well and works. However, if you want to train chord analysis in any key besides C major you have to pay for a monthly subscription. That’s ridiculous. 

I understand advanced study features being in a subscription, but other key signatures is silly. Other keys are a part of music, not just C major.

**Developer response:** Thank you very much for your message and interest in our app.

### 5/5 — 素早い対応ありがとうございます。

*2024-10-27*

不具合の対応をすぐ行なっていただき助かりました。ありがとうございます。

隙間時間に簡単に復習、反復練習が出来ます。
解説はないので、ある程度以上知識がある前提の問題集です。
専門的に学んでる人が数をこなす為のツール（基礎）としてとても有効かと思います。

昔勉強したけどもう離れている方などは、パズル感覚で思い出しながら楽しめるかもしれません。

**Developer response:** メッセージ、ありがとうございます。私たちのアプリがお役に立てれば何よりです。よろしくお願い致します。

This app is a great way to learn your chords. It is simple, robust and well written, and has positive comments when you start it up.

**Developer response:** Thank you very much for your message. We are glad to hear that the app works well for you.

### 3/5 — 和声記号を当てるアプリです

*2018-05-03*

アプリ説明にある「和声の問題」とは和声の接続や禁則についてではなく、楽譜に記載された和音を「和声記号でどう書くか？」を答えるアプリです。

また、解説は一切無いため、既に別の本で学んでいる事が前提となっています。

なお、私はこの表記方法を学んだ事が無かったため、役に立ちました。
(以前、芸大和声と呼ばれていた赤本、黄色本、緑本と異なる記法を学べます)
