今更ながら感謝を

再度のレビューしつれいします。メールも以前おくったのですが、私がカポ機能の追加について失礼な態度で頼み込んでしまったのに対して、真摯に対応してくださり、機能を追加してくださったことに今でも感謝しきれません。無料でこれだけ良い機能が使えるアプリはこれだけだと思います。もっと広まって欲しいと切に願います。ありがとうございました。

Very useful!

Been using it for years. Tons of alternative tunings! Highly recommend.

Do not recommend

First thing I went to the app I was confused about the e string I don’t know what was the “e string” do not recommend 😭

んー

iPhoneの機種の問題かもしれませんが、自分のスマートフォンではチューニングが合いませんでした。
針が右に行ったり左に行ったりして中々チューニングできません笑てかできません笑

しかし良い点を言えばチューニング出来る種類が多いのでは無いでしょうか、ドロップCのチューニング出来るアプリはこのアプリぐらいしか見かけませんでしたし。

機種変したらまた入れたいと思います〜

長文失礼しました(・д・。)

415HZがほしい。

415HZがほしいです。
