### 4/5 — 海辺が好きです

*2021-01-17, version 1.1.0*

海辺が好きですね
綺麗で少し控えめ🤏でもとても美しくて
よく眠れます。
星一つないのは…無課金でこれだけ使えれば十分なのですが…もうちょっと増やして欲しいのと，タイマーをもうちょっと範囲を広げて，細かい時間設定まで出来ると嬉しいです😊

### 4/5 — 良いと思います。

*2020-05-19, version 1.1.0*

たくさんの音の種類があって、その時に聴きたい音を選んで聞けるのが良い。
さらにタイマー設定ができるのも良い。
聴き流し程度で毎日聴いてます。
気のせいという事もあるかもしれないが、音サプリを使っている時は他のアプリの通知の音が消極的になっていると思う。
あと、充電しながら音サプリを使うのは余りお勧めしません。（充電が進まないです。）

### 5/5 — 良い。

*2019-05-21, version 1.1.0*

毎日聴いています。

### 3/5 — いいね

*2019-04-29, version 1.1.0*

うん、無課金でこれだけ使えれば上等

### 4/5 — ほぼ良い！

*2018-11-20, version 1.1.0*

タイマーが使えないことだけが惜しい

### 2/5 — タイマーが使えない

*2018-09-09, version 1.1.0*

iPadで使用しているせいか、タイマー部が画面外になってしまいます。スワイプしてみても反応はなく…。
機能的には必要十分、シンプルでとても良いのですが、寝る前に使えないのは痛い。改善していただけると有り難いです。

### 5/5 — こいつは いい 作業用BGM だと思う

*2018-01-19, version 1.1.0*

とても集中できます ありがたい
特に秋の音がとても気に入りました
ちょくちょく使わせて貰っております

### 5/5 — 小川が好き

*2016-10-01, version 1.1.0*

小川の音がうるさくなくて
タイマーセットも簡単シンプルでいいと思います！

### 5/5 — いいね！

*2016-09-02, version 1.1.0*

その場にいるような気分に浸れて寝ちゃいます。
癒されたい方は是非。

### 4/5 — 無料アプリの中では優秀だと思います

*2016-09-01, version 1.1.0*

寝る前にタイマーをかけて使うことができ、違う画面を見ながらでも普通に使えるので使いやすいです
他のアプリのように小動物の鳴き声と組み合わせられたりするともっと良いなと思います。
近いうちに雨の音を追加していただけることを期待しています。
