User reviews

軽快に動く。プロットも設定まとめもぜーんぶこれでいいわ!

多機能だけど立ち上げが早い。他の多機能型の小説執筆用アプリに比べて操作が軽快なので嬉しい。
必要な項目だけを状況に応じて表示して使えるUIが気に入っている。登場人物や設定などをこれひとつでまとめられるので助かっています。

初期設定のまま、メニュー?を表示した状態でiPadのキーボードで使用していると、矢印キーで行間移動ができない。この点だけがネックかも。
バグ報告もしたいのですが、メールだと恐縮するので、会社HPに簡単なフォームがあるとありがたいです…

課金もサブスクじゃなくて買い切り型。無料でも便利だけど、充分にお金を払う価値があるアプリ。

Response from developer

温かいレビューをありがとうございます。軽快さと、必要なものだけを出す画面を気に入っていただけて、とても嬉しいです。 iPadの外付けキーボードで、左側の一覧(メニュー)を表示していると矢印キーで行を移れなかった件は、バージョン1.2で直しました。ご報告ありがとうございました。 不具合のご報告やご要望は、フォームからも送れるようにしました。アプリの「設定」→「お問い合わせ」から開けます。お使いの端末とバージョンが書き込まれた状態で開くので、起きたことを書いていただくだけで大丈夫です。原稿帖のサポートページにもフォームを置いています。 また何かありましたら、お気軽にお知らせください。
