Store description

世界初のAIベースの英単語作成アプリ。 英語に真剣に取り組んでいるなら、WordUp の虜になるでしょう。 これは英語を完璧にし、そのプロセスを楽しみながら重要な単語をすべて学ぶための最も賢い方法です。 - 語彙ビルダー WordUp の語彙ビルダー機能は、高度なアルゴリズムを利用して語彙を増やし、英語スキルを向上させます。 現在の知識に基づいて毎日新しい単語を提案してくれるので、徐々に言語能力を向上させることができます。 WordUp は、毎日の単語を学習ルーチンに組み込むことで、着実かつ一貫して語彙力を向上させます。 - ナレッジマップ WordUp は、知っている単語と知らない単語を識別することで、知識のマップを作成するのに役立ちます。 語彙のギャップを特定し、注目すべき最も重要で役立つ英単語を提案することで、新しい単語を学習するのに役立ちます。 毎日の語彙を取り入れて進捗状況を追跡することで、ナレッジ マップを使用して語彙を着実に増やし、英単語の理解を強化することができます。 25,000 の便利な英単語はすべて、実際の英語での使用頻度に基づいて、重要性、有用性の順にランク付けされています (数千の映画やテレビ番組から抽出)。 ナレッジ マップで見つけた単語を実際に学習するために、WordUp には必要なものがすべて揃っています。 単語の定義や写真から、映画、引用、ニュースなどの数十の面白い例まで。 したがって、文脈の中で各単語をどのように使用するかをよく理解できます。 - 多言語翻訳 フランス語、スペイン語、ドイツ語、アラビア語、トルコ語、ペルシア語などを含む 30 を超える言語への翻訳もあります。 その後、毎日のレビューが始まります。単語はフラッシュカードのように、マスターするまでゲームや課題とともに戻ってきます。 これはSpaced Repetitionと呼ばれるもので、永久に暗記するのに役立つことが科学的に証明されています。 WordUp は、これまでに見たどの語彙ビルダー アプリとも異なります。 これは別の辞書アプリではありませんが、英語辞書としても使用できます。 - さまざまなユーザーに適しています 言語学習と語彙の拡大に対する WordUp の斬新なアプローチは、自信と力を与えてくれます。 英語に慣れていない人、英語試験 (IELTS、TOEFL など) の準備をしている人、または英語を母国語とする人であっても、WordUp は役に立ち、楽しいものであることがわかります。 試してみてご自身の目で確かめてください。
