If you go to bed late at night or stay up all night, you may not be able to manage your daily tasks sufficiently with the notation of 1 day = 24 hours. With DaySche, you can input tasks for up to 48 hours, so you can manage tasks up to two all-nighters with a single flow. DaySche Features Super simple task management All you need to enter is the task name and start time! You don't need to fill in everything like in a pie chart, just enter the time you want to put the task in! Up to 48 hours Ignoring the concept that a day = 24 hours, you can manage your tasks in one flow, whether you are a night owl or an all-nighter at work. Templating Tasks Frequently used tasks can be saved as templates and registered with a single tap. Separate by day of the week! Or divide by task content! *This app is not a calendar or other schedule management app, but an app for managing the flow of tasks in a day, from waking up to going to bed. If you are looking for a schedule management app, please check LooSche, an app with the same color scheme and design.

集中する=深海へ潜る。新感覚の集中タイマー スマホを置いて集中するたびに、あなたは深海へと沈んでいく。 1分の集中 = 1mの潜水。25分のポモドーロで25m。積み重ねた集中が、深海への旅になる。 【深海生物との出会い】 タイマー完了のたびに、深度に応じた生物に遭遇。表層ではクマノミやマンタ、深くなるほどチョウチンアンコウやメンダコなど幻想的な生物が現れる。完全集中(アプリを離れない)だとレア出現率2倍! 【あなただけの水槽】 出会った生物が「マイ水槽」に住み着く。横スクロールで水面から深海まで、ゆらゆら泳ぐ生物たちを眺めよう。深く潜れば潜るほど、水槽が豊かになっていく。 【罰しない設計】 途中でやめても、生物は死なない。完全集中を達成すると、よりレアな生物に出会いやすくなるだけ。プレッシャーなく、自分のペースで続けられる。 【深海図鑑】 30種以上の深海生物を発見しよう。未発見の生物はシルエットで表示。「深度1000m付近に生息」のヒントを頼りに探せ。 【記録・統計】 週次グラフでカテゴリ別の集中時間を可視化。連続日数(ストリーク)で継続のモチベーションを維持。累計深度があなたの努力の証。 【シンプルな操作】 (1) 「潜る」ボタンをタップ (2) カテゴリ(勉強/仕事/読書/その他)と時間を選ぶ (3) スマホを置いて集中するだけ 対応タイマー: ポモドーロ(25分)/ 集中(50分)/ ショート(10分)/ カスタム(1〜180分) BGM: 深度帯ごとに自動切替(波音 > 水中反響 > 低音ドローン) 【プレミアムプラン ¥380/月 / ¥3,200/年】 - 広告完全非表示 - BGM全15種 - 水槽カスタマイズ(背景・光源の色変更) - 図鑑の詳細情報(豆知識・実際の映像リンク) - 高解像度水槽エクスポート(透かしなし) - カテゴリ数無制限 - 集中統計の詳細分析 Forest・gogh・魚が育つアプリの次を探している人に。 深海という比喩が、集中するほど正しくなっていく。 利用規約: https://qtarou11111.github.io/abyssal-web/terms.html プライバシーポリシー: https://qtarou11111.github.io/abyssal-web/privacy.html
