「かきみほん」は、紙に文字を手書きするとき、iPhoneを横に置いて見ながら書くための文字見本アプリです。 病院の問診票、役所の申請書、配送伝票、各種申込書など—— 「普段はスマートフォンばかりで、いざ紙に文字を書こうとすると漢字の細部が思い出せない」 「小さく表示された文字だと、細かなハネやつくりが見づらい」 そんな場面で、書きたい文字を入力するだけで、画面いっぱいに大きな見本を表示します。 文字の練習帳や漢字辞書ではなく、書く直前の「手元の見本」として使うことだけに特化しました。 ◆ 主な利用シーン ・病院やクリニックの問診票・同意書の記入 ・市役所・区役所などの各種手続き書類 ・宅配便や郵便の送り状・伝票 ・銀行や各種サービスの申込用紙 ・のし袋や手紙の宛名・芳名帳の手書き時 ◆ かきみほんの特徴 1. 入力して閉じるだけのシンプル操作 文字を入力してキーボードを閉じると、余計な枠や装飾が消え、文字を大きな見本として表示します。 2. 手書き中に画面が消えない 見本を表示している間は画面の自動スリープを防止。書き写している途中で画面が暗くなりません。 3. 縦画面・横画面の両方に対応 iPhoneを横向きにすれば、横長の画面を活かして文字を確認できます。 4. 「縦に見る」に対応 縦画面では、漢字・ひらがな・カタカナを上から下へ並べて表示できます。 5. 書き文字と明朝体から選べる 見本の字体を、書き写しやすい「書き文字」と「明朝体」から選べます。あとから設定で変更することもできます。 6. 広告なし・登録不要・完全オフライン 広告は表示しません。アカウント登録やログインも不要です。入力した文字は保存せず、外部へ送信することもありません。オフラインで利用できます。
