Doit は「ひとつのタスクに集中する」ためのアプリです。 あらゆるタスクは、「始められないこと」こそが最大の障壁。始めさえすれば、終えられるかどうかは重要ではありません。 Doit では、マルチタスクを避けるために「今やるべきタスクをひとつだけ」登録します。あとはアプリが、あなたをそっと導きます。 たとえば「勉強する」というタスクを登録したら、こんなステップが表示されるかもしれません: ・足の指をモゾモゾさせて ・昨日の晩ごはんを思い出して ・机の角を触る 一見すると意味のない行動に見えても、それらはすべて「始める」ための準備です。身体や感覚をゆっくりと切り替え、やるべきことへ自然に向かわせてくれます。 脇道に逸れず、ひとつずつ。 本当に向き合いたいことだけに集中できるように設計されたアプリです。
