### 4/5 — バッテリー節約のため

*2024-09-21, version 1.0.2*

被災時に、笛などを持っていない場合、このアプリを使って音を出そうと考えています。
ホイッスルとライトの点滅をさせることができますが、アプリを開いているときにしか動作しません。アプリを閉じた状態でもバックグラウンドで笛の音がなったり、ライトの点滅ができるように改善いただけると実用性が上がると思います。ぜひご検討いただきますよう、よろしくお願いいたします。

スポーツの大会で使いたかったのですが、開かず削除しました。

### 5/5 — いいね！

*2018-11-16, version 1.0.2*
