いろんな日記アプリや気分を記録する日記アプリを使ってみたけど、どれも続かない・・・ でも、開いてすぐに書くことのできるチャットのような見た目のアプリなら、普段使っているSNSのように無理なく続けられるはず! 書いた内容はスマホにのみ保存されるので、あなた以外の誰も見る事はできません! 思う存分、好きなだけつぶやきましょう! ◆開いてすぐ書ける! 煩わしい操作をせずにアプリを開いた瞬間、その時思ったことをすぐに書くことができます。また、気分も同時に記録されるのでとても簡単!シンプルなメモ帳としてもご利用いただけます!画像を貼ったりタグを付けられたりできます。なんとToDo機能までついています! ◆誰にも見られない! 書いた内容は端末内にのみ記録されるので誰にも見られません。SNSのように誰かに気を遣って何も書けない!ということはこのアプリではありません!楽しかったことも嬉しかった事も、不満を感じた事も、悩みも、このアプリなら本音を自由に言えます!パスコードロック機能も搭載しています ◆背景画像を設定できる! お手持ちの好きな画像を背景に設定できます。好きな画像を設定しましょう! ◆1日の気分の流れを一目で見れる! 「はぁ。今日は休みなのに何もない一日だったなぁ」と落ち込む事もあると思います。ですが、細かく振り返ってみると、実は小さな喜びや悲しみが沢山あったりします。振り返りを容易にするために、その日の感情の動きをチャートで確認する機能を用意しました!本当に何もない日なんて、意外とないのかもしれませんね。 まだできたばかりで機能が少ないですが、今後はさまざまな便利機能を追加する予定です!
