考えたいことを無理なく考え、忘れないでおくためのアプリです。 本アプリでは考えたいことを記録し、ランダムに表示することができます。 忙しさや不安に押しつぶされて、自分との対話を忘れてしまう瞬間はありませんか? 大事なことほど、すぐには答えが出ないものです。 また「問われて、考え続けて、はじめて気付くこと」も世の中には多いと思います。 本アプリは、自分のための「質問(問いかけ)」を記録しておき、一日一問くらいの気持ちで「無理なく考える」ことを支援するためのものです。 以下のようにシンプルな機能しかなく、気軽に使っていただけます。 主要な機能 ・考えたい質問を記録しておけます。 ・考え中の質問をランダムに表示できます。 ・思いついたことがあればメモを残しておけます。 ・行き詰まった質問は除外に、考えがまとまったものは回答済みにステータスを変更できます。 ・デフォルトの質問から、質問をインポートできます。 ・クリップボードコピー等で、別サービスに記載内容を移すことができます。 ・バックアップ・復元機能があります。 ユースケース ・例えば、「近々ブログを書こうと思っているけれど、ネタがない」とき。  ・本アプリに「ブログのネタは?」と書いておきます。 ・あとは、隙間時間にアプリを開いて、思いつくものがあればメモを取ります。  ・隙間時間や開くタイミングの例   ・朝起きたとき   ・通勤中   ・散歩中など しばらくしてメモがたまったら、ブログを書けるようになっているはずです! ・クリップボードコピーなどを利用して別ツールで内容を深堀りしてもいいと思います。 ・メモが書けなかった場合は、別の質問を考えて本アプリに登録してみます。  ・例えば「最近気になっていることは何か」など。 【利用規約】 https://beeeyan-app-introduction.web.app/explore-yourself/agreement
