Would be of use if it had an Apple Watch component, but sadly it does not!! ### 3/5 — バックグラウンド機能 *2021-05-18* アプリを開いていない状態、またiPhoneがスリープ状態の時でも動作できるようにしていただきたいです😭😭😭 ### 1/5 — おかしい所山盛り *2021-01-29* バイブをオンにしたら声で停止の設定が出来ないのは何故？ わざわざそんな制限設ける必要ありますか？ 不便です。 あと、ボタンで停止、機能してない。停止ボタンが表示されない。 「終了」ボタンはあるけど、繰り返し自体も終了するから意味がない。 さらに言えば、サウンドとバイブ両方オンにできてもいいのでは？ ガチガチに制限設けて誰が幸せになるの？ さらに、サウンドの音が微妙すぎる。 あのチョイスどういうセンスなのか、、、 ### 1/5 — ウォッチにも *2020-07-15* アップルウォッチに対応して欲しいです。 ### 3/5 — Needs or more intense or alternate vibrations. For narcolepsy. *2020-03-08* Good app but need a bit more in wake ups if I fall asleep in a chair vibration won’t wake me. Need strong sound. Maybe Bluetooth to speakers. ### 4/5 — 🇯🇵 *2018-05-28* ストップボタンが小さい。 画面のどこを押しても止まるようにして欲しい。 ### 4/5 — よい *2018-05-12* アプリを閉じた状態、及びスマホをロックした状態でも動くようにして欲しいです ### 3/5 — 活用しています *2017-06-27* 携帯の画面を常に見ていなくても良いように裏でも動くようにして欲しいのと、バイブがささやか過ぎて本当にウトウトしてる時は気がつけない時があるので、数段階選べるとありがたいです。 ### 1/5 — ？？ *2016-08-25* せっかく、いいアプリ見つけたと思ったんだけど全くバイブが動かない！？！！！！？ ### 2/5 — 最低 *2016-04-21* クルマの中で試したが 一切動かなかった… なんで？ ## Frequently asked questions about Doze Prevention ### How does Doze Prevention work?
