Great music player

I’ve used this app for years. I tried out a number of the competitors before discovering KaiserTone. This one is my favorite.

バージョン3.7.9で起動時にアプリ終了。

早速アップデートしたところ、iOS16環境ですが 起動時に落ちてしまいます。 Twitter の接続準備が出来ていないメッセージ画面のOKボタンを押すとアプリが終了してしまいます。本アップデート前迄は使用に問題は有りませんでした。

2026年10月30日追記

最高のミュージックプレーヤーです。

Good but needs fresh Design

Good App and Great eq. But the Layout feels old and needs retouch.

1万円ぐらいの値打ちがあるのでは...?

昔から愛用しているアプリです。所持している音源を極めて高音質で聴けることは、皆さんの仰る通りです。イコライザも非常に細かく調節できるため、突き詰めれば恐ろしいほどの高音質を実現できます。また、ワイヤレスイヤホンで音楽を聴く際は音量を段階的にしか変えられないのが悩みですが、このアプリだと音量設定の「Gain」の項目を使えば、ワイヤレスイヤホンでもシームレスに変更できるので、それも非常に有難いです。

1点だけ、このアプリの問題点への対処法を見つけたので、ユーザーの皆さんに向けてシェアしたいと思います。アーティストの欄で、各アーティストのアイコンとして表示される画像は、ライブラリにあるアルバムの中から自動的に1つ選ばれる仕様なのですが、それを自分の好きなものに変更する方法がなく、お困りのユーザーさんもいらっしゃると思います。私が検証した所、「ライブラリ内のそのアーティストの曲を全て五十音順に並べたときに、一番先頭に来る曲のアートワークが選ばれる」という法則であることが分かりました。対処法としては、「iTunesなどで、アイコンとして表示させたいアルバムの曲を1つコピーし、タイトルを『アイコン設定用ファイル』『アートワーク設定用ファイル』などに変更してライブラリに追加する」という方法でとりあえず解決したので、お困りの方は試してみてください。
