User reviews

素晴らしいアプリです。

車のNVHを測定したくて購入しました。UIの優れた多機能なアプリで車内騒音を簡単に計測でき、車のSNS みんカラに投稿させて頂きました(Googleで「ZR-VのNVH」で検索すれば、最初に出てくると思います)。ただ、使い方が間違っていないか少し不安ですので、コメント(みんカラのコメントでも結構ですので)を頂けると嬉しいです。今後のバージョンアップも宜しくお願いします。

Bring back the previous colour scheme and icon.

New ones are dull, pale and uninspiring

200Hz未満も表示して欲しい

1/3オクターブバンドやFFT表示の時に200Hz未満の周波数も測定・表示して欲しい。(可能であれば0㎐から)
一番測定したかった周波数帯がその辺りだったため。また最大測定値の履歴が表示される機能もあると便利だと思った。
(他の無料アプリで付いていた機能)
計測時間もエンドレスが欲しい。これらの機能付加を切に望みます。
測定器は買うと高いが、このアプリは手軽で使いやすく便利なため、今後のアップデートに大いに期待しています。

車内の騒音計測に使用

時系列計測は大変よい機能だと思います。不満な点は画面から消えてしまった時間の計測結果が遡って見られないことです。計測結果を保存できるとなお良いと思います。

Bug in version 1.2

Ver 1.1 was great; everything worked. Ver 1.2 stops sampling when iPhone locks. Must keep iPhone unlocked to use-- no good. Have reverted back to ver 1.1.
