Based on your preset ideal bedtime, wake-up time, and sleep duration, the app evaluates your achievement. Meeting the conditions counts as a success, extends your streak, and unlocks badges. Notifications sent 30 minutes before your planned bedtime and at wake-up time naturally prompt you to take action.

「残り時間を知ることで、今日の解像度が上がる」 LifeTimer は、memento mori(死を想え)の思想をベースに、人生における様々な「残り時間・残り回数」を可視化するアプリです。 ■ こんな“残り”が見えます ・お母さん/お父さんと過ごせる時間 ・富士山に登れる体力が残っている年数 ・海外旅行に行ける回数、これから読める本の冊数 ・子どもに「抱っこ」とせがまれる回数、寝顔を見られる夜 ・今年の夏はあと何日 …など50種類以上 ■ 特長 ・あなたの生年月日・家族構成に合わせてパーソナライズ ・時間は「年・日・時間・分・秒」で刻一刻とカウントダウン ・自分のペースに合わせて数値を調整できる ・偉人・作品の名言(今日の一言)で、そっと背中を押される ・ホーム画面ウィジェットでお気に入りのタイマーをいつでも ・落ち着いたクリーム×ゴールドの世界観 ■ ごあんない 表示される数値は公的統計等をもとにした一般的な参考値であり、個人の寿命や健康を診断・予測するものではありません。あくまで「今日を大切にするきっかけ」としてお使いください。
