寝る前だけどついついスマホを見て、目が冴えてしまう・・・ Necomiはそういった方の慢性的な寝不足を防ぐための寝落ちアプリです。 ▶超ダークモード iPhoneの明るさ設定とは独立して、このアプリ単体での明るさ設定ができます。 また、iPhoneで明るさを最小にした場合よりも更に暗い画面設定が可能になっております。 このアプリで明るさを最小にした場合、ほぼ完全に真っ暗な画面となります。 ▶寝落ち検知スリープ 動画サイトではiPhoneが水平になったことを検知して再生が止まり、その後しばらくしてスリープします。 寝かけたところでいきなり大音量のサウンドが流れ始めて目が覚めた!といった事が起こりません。 通常の動画再生アプリと異なり、動画を夜通し再生し続けてバッテリーが切れる心配もありません。 ▶寝落ち記録 寝落ちた次の日、何をどこまで見ていたか思い出せないことがあります。 記録をたどれば簡単に続きから見ることができます。 ▶横向きロック ごろごろ寝返りしても横画面の状態がキープされる機能です。 横向きロックはiPhoneのみ対応です。 ※Amazon Prime Video, Netflixはこのアプリ上では再生できません。各サービスの専用アプリをお使いください。
