当該アプリケーションは学習者と教師が好評の New General Service List（NGSL）を利用することに役立つように設計される。 アプリにNGSLをダウンロード、eメールそして組み合わせするための簡単なツール、そして単語を迅速そして効率的に学習し、進捗度を詳しく記録するための学習ツール、進捗度をご自分または教師にeメールする機能が含まれる。 単語の解釈は簡単な英語で書かれて、一部スピーチ付きである。それにその単語の日本語訳と英語のネイティブスピーカーによる発音も提供されている。 インテリジェント・フラッシュカードについて： 本アプリもインテリジェント・ワードリスト・メーカーとインテリジェント・フラッシュカードシステムを含む。 インテリジェント・ワードリスト・メーカーがあれば、フラッシュカードシステムの中に知らない単語だけ迅速と効率的に選んで勉強することができる。全部のリストを一回通すことを強いるより、インテリジェント・ワードリスト・メーカーは頻度順でリストを通すことをガイドしてもらい、必要に応じてまたは暇があるときに少しずつ単語を追加することを可能にする。 すでにドキュメントされた科学である「間隔反復」に基づき、インテリジェント・フラッシュカードシステムは一ヶ月の期間において単語を数回復習することに系統的そして効率的に役立つ。それで、難しいと感じる単語にもっと時間をかからせてもらう。 The NGSL is an open source free access wordlist and is used with permission.

Withstory holds the better App Store score, 4.3 against 3.8.

Written reviews complicate that: 54% of NGSL Builder 日本語版's written reviews are positive against 0% of Withstory's, so the app with the better star average is not the one people write more warmly about.
NGSL Builder 日本語版 ships an update every 8 months, Withstory every 3 months. The most recent releases landed on October 16, 2026 and October 5, 2026 respectively.
