実技（記述問）対策アプリ。このPLUS版（課金）と通常版（無料、App内課金）の二種類を用意しています。例題は、何れの版も同じものを使用しています。 PLUS版は、Expandable cellsを使用し、操作性に重点を置いた作りとし、通常版は、オーソドックスなmaster-detail版としています。 何れも、豊富な例題の中からカテゴリ・サブカテゴリ検索、更には任意の単語で自由に検索を行える問い・解答例検索等を活用することにより、より迅速に類似の例題を検索することが出来、記述問に関するスキルを習得し、回答時間の短縮を目指します。 App内課金機能では、未課金の状態で例題の解答例の一部のみ表示します。 （このアプリは、「一般財団法人気象業務支援センター」・「気象庁」とは関係ありません。また、例題の正確性、最新性、 有用性等その他一切の事項について、いかなる保証もするものではありません。）
