Read full descriptionHide full description
これまでのスキャンアプリとは少し違ったアプリの登場です! iPhone iPadのカメラがスキャナに大変身。 ARでスキャン領域を表示し、その枠内の画像をスキャンします。 1,書式サイズを予め決めてからスキャンするのでトリミング作業が不要です。 ※手動でトリミングも可能 2,トリミングは撮影ポジションで決まりますので、慣れれば今まで以上に早いスキャンができます。 3,文書を真上から撮影する必要が無いので、座ったままスキャンできます。 4,スキャンした後の画像処理機能搭載。 ※2値化、濃淡補正、モノクロ化など 5,スキャン時にスキャナの動作音がするので、仕事している感をアピールできます! ※マナーモードでは動作音は鳴りません 6、アプリを起動してすぐ使えるシンプル設計。スキャンした画像はカメラロールへ保存されます。 7,ユーザの要望に応じて今後バージョンアップします。 皆様のご要望、ご感想を心よりお待ちしております。m(_ _)m

Verdict
The clearest difference is in-app purchases: カメラスキャン at none against QuietAlert's 3. カメラスキャン also leads on iOS requirement (8.0 vs 26.0). QuietAlert's advantage is update cadence (every 12 months vs every 27 months). On price, ads and device support there is nothing between them.
