「止める」=「起床完了」ではありません。 オキロは、二度寝を構造的に防ぐことだけを考えた目覚ましアプリです。「絶対に起きる(スヌーズ)」をONにすると、アラームを止めても「起きた」ボタンを押すまで鳴り直し続けます。止めて安心して二度寝、を仕組みで無くします。 ■ 起床保証 止めても終わらない追撃チェーンで、起きたことを確認するまでアラームが鳴り続けます。普段使いのアラームは、押すだけで完了する通常の目覚ましとして使えます。 ■ カレンダー連動 毎日同じ時刻ではなく、「予定がある日」「予定の◯分前」に合わせて自動でアラームを設定できます。祝日は自動でスキップ。 ■ 自宅モード 複数の場所を「自宅」として登録し、位置情報で自動的にモードを切り替え。「自宅にいる時だけ」「外出時だけ」有効なアラームも作れます。 ■ 好きな音で 本体の着信音でも、バックグラウンドでも確実に鳴るイヤホン向けの専用音源でも。用途に合わせて選べます。 ■ ショートカット連携 「次のアラームを取得」「起床確認待ちか調べる」など、ショートカットアプリと組み合わせて自分だけの自動化も作れます。 ■ 完全無料・広告なし すべての機能は無料でお使いいただけます。広告は一切表示しません。気に入っていただけたら、開発者への任意の応援(チップ)だけご検討ください。機能の制限や見返りは一切ありません。
