### 4/5 — 良い

*2026-07-23*

大変使いやすい良いアプリですが、残念ながらiPhone15proMAXでは左側がはみ出してしまい正常に表示されません。惜しい

### 4/5 — 6thのコードがつかえない

*2026-04-04*

使いやすくコード進行作成に役立っていますが、シックスのコードが使えないのが残念です。

**Developer response:** コード進行メモをご利用いただきありがとうございます！

6thコードはテンションノートタブ(キーボード左の"9 11 13"と書いてあるところ)から13を押すことで入力できますので、ご活用ください。
より良い入力方法は検討中ですので、リリースまでしばしお待ちください。

### 1/5 — 正常に機能しなくなった

*2026-03-10*

メモを選択するとfailed to setupというエラーが出てアプリが落ちるようになってしまった

**Developer response:** コード進行メモをご利用いただきありがとうございます！
バグを修正しましたので、アップデートお願いします。

### 1/5 — バグ

*2026-02-22*

failed to setup と言う文字が出てきて使い物にならない。再生してもすぐ落ちる。

**Developer response:** コード進行メモをご利用いただきありがとうございます！
バグを修正しましたので、アップデートお願いします。

### 4/5 — 急に

*2026-01-31*

何も曲が再生されない

### 4/5 — 優秀

*2023-12-18*

コード進行作成に役立っています。
類似アプリに比べるとテンポや拍子をファイルそれぞれに保存でき、曲中に変更できるのが凄く良いです。
正しいキーを設定すれば移調やディグリー表示できるのも評価点。
また粗いボイシングはこういったアプリの宿命ですが、CからBへ移行しても比較的自然に聞こえるのも良いところだと思います。
ただし素早くコードチェンジしたりすると音が消えるのは気になります。
複雑なコード(♯9や♭9など)もある程度対応してるので思いついたものは大抵表現できます。
惜しむらくは6thが(13)表記で固定になったりsus2は表記できないところでしょうか、sus4を転回すれば音は一緒ですがコードネームが不自然になります。
またm7(♭5)を入力の仕方が初見だと分かりにくく、このコード以外は5度を変位できないので耳コピ等では表現できないこともたまにあるが気になります。

### 4/5 — ボイシング変更

*2023-12-07*

ボイシングを変更できる機能がほしい

### 5/5 — Cool app

*2023-07-14*

Nice work on this app

### 5/5 — とても使いやすいです！

*2023-04-02*

感覚的に使えます。
Ⅳ♯m7（♭5）のような、フラットファイブのボタンができると嬉しいです！
