集中力タイマーはポモドーロテクニックを使用したタイマーです。 タイマーを開始したらポケットへ。残り時間はロック画面に表示され、セッションの終わりはアラームが知らせてくれます。 ■ ロック画面で完結 残り時間・セッション(作業/休憩)・セットの進み具合を、ロック画面と Dynamic Island でいつでも確認できます。 ■ アラームで確実にお知らせ セッションの終わりはシステムアラームでお知らせ。サイレントモード中でも鳴るので、通知を見逃してそのまま作業し続けてしまうことがありません。 ■ 止めた瞬間が、次のはじまり アラームを止めたその時点から、次のセッションがまるごと始まります。気づくのが遅れても、休憩時間が削られることはありません。 ■ 自分のリズムに合わせて設定 作業時間・短い休憩・長い休憩・長い休憩までのセット数を、1分単位で自由に設定できます。定番の「25分作業+5分休憩×4セット」はもちろん、自分だけのリズムで。 ■ 今日の積み重ねがひと目で 完了したポモドーロの数を画面にさりげなく表示。小さな達成の積み重ねが続ける力になります。 ■ シンプルであること 広告なし、アカウント登録なし、データ収集なし。タイマーに必要なものだけを、iOSの新しいデザインでつくりました。 -------------------------------- ポモドーロ・テクニックとは -------------------------------- 「25分の集中+5分の休憩」を繰り返し、数セットごとに長めの休憩を取る時間管理術です。短い集中を積み重ねることで疲れにくく、無理なく続けられるのが特長です。 こんな方におすすめです ・勉強や仕事中、ついスマホを触ってしまう ・タイマーの通知に気づかず、作業しすぎて疲れてしまう ・多機能すぎるアプリではなく、シンプルで美しいタイマーがほしい
