このアプリは、毎日の気分の変化を記録し、その推移を可視化することで、自身の感情の動きを理解するためのツールです。前日と比べて今日の気分がどう変化したかを記録することで、長期的な心の動きを把握することができます。 よくある感情記録アプリは、今の感情を5段階(とても良い〜良い〜普通〜悪い〜とても悪い)などの絶対的な値で記録していきます。それにはいくつかの問題があります。 ・今の気分を絶対的なものとして記録するのが苦手な人がいる(感情を客観的に捉えづらい人がいる) ・昨日が感情のピークだったと思ったのに、今日はそれを上回る好調だった場合、5段階よりも上を選びたいが、それは不可能 ・気分が明るいことが必ずしも良いとは限らない人もいるが、既存アプリではそれを考慮していない 「これだけ良い」「これだけ悪い」という絶対値ではなく、前日との比較で相対値を記録していくことにより、それらの問題を解決できると考えています。 新しい試みをしているので、皆さんのご意見をうかがいたく、まずは無料で公開しております。

Done Diary is a simple diary app for recording what you accomplished today and giving yourself credit for the small things. It is not made to push you to do more. It is made to help you notice what you finished, what you kept up with, and the small steps you took today. You can record what you did today, things you want to do later, and daily habits. At the end of the day, you can also add your mood and a short note to gently reflect on your day. Your records can be reviewed in Days by month. Use the list or calendar view to look back on what you have been building over time. Recommended for people who: ・want to focus on what they did, not what they could not do ・want a diary that is easy to continue ・want to track habits and small actions gently ・want to end each day with a little more self-recognition Done Diary is not about trying harder. It is about noticing what you already did today. Keep small records, and look back on your everyday progress.
