### 5/5 — q

### 5/5 — 使えない

*2026-03-26*

CSVファイルをインポートしようとするとアプリが落ちます
Webからのインポートもうまく行きません

追記:使えるようになりました!ありがとうございます

### 4/5 — 見やすくて大変便利

*2025-12-07*

インポートも早く、譜面の確認のためにYouTubeに繋がるとこも便利です
たまにクリアレート%が表示されない曲もありますが…概ね良好です

クリアレートが小数点以下まで表示されること、次のレートまでのスコア数(例:A+◯◯、AA-⬜︎⬜︎)などが確認出来るとさらに便利になると思いました

### 3/5 — 今後に期待

*2025-11-08*

たまにスコアレートが96.8%とかでも97%表記になってるのが気になるところ。正確に小数点の部分までスコアレートを見れるようにしてくれると嬉しいです。
あと個人的に難易度→ハイパー、アナザー等の表記でレベル→1〜12の表記の方が正確じゃないかと思います。
開発も大変かと思いますが、今後も使わせていただくと思います。

### 2/5 — DPは未対応

*2025-10-02*

DP用のCSVを取り込んでもDPデータには反映されず。逆にSPデータを上書きしてしまうため危険。DPタブがあるのに機能していないため非常に残念。
SPだけ使うなら問題ないかも。

**Developer response:** この度ご不便をおかけし申し訳ございませんでした。
バージョン33.0.3には該当する不具合の修正が含まれています。
再度お試しいただけますでしょうか？
お手数ですが、よろしくお願いいたします。

### 1/5 — インポートが

*2025-09-29*

インポートがうまくできなくて使えませんでした…
残念

**Developer response:** 大変お待たせしました。
2026年3月19日にリリースしたバージョン33.2.2でこの不具合を修正しました。
お手数ですが、アプリをアップデートしてから再度お試しください。
ご不便をおかけし申し訳ございませんでした。

### 1/5 — インポート中にエラーでアプリクラッシュする

インポート始めた瞬間にアプリクラッシュする

**Developer response:** 大変お待たせしました。
