"Just one more battle." Before you know it, you know more words than you did yesterday. The joy of winning a quick match overlaps with the pure satisfaction of realizing you actually remembered the word when it mattered. ■ 50-second real-time vocabulary battles Jump into quick 50-second quiz battles against friends or other players in real time. Each match is fast and focused, making it easy to fit meaningful vocabulary practice into short breaks during your day. You can compete in the Citizen League rankings, or choose to practice comfortably without joining the league. ■ Adventure mode with instant explanations Meet each word naturally in Adventure mode. Learn vocabulary through clear pictures, audio pronunciations, and example sentences while answering quizzes. If you make a mistake, explanations appear immediately so you can correct your understanding on the spot. You can also look up words anytime using the built-in dictionary. ■ Smart word books and custom review Keep your vocabulary organized automatically. Your word book sorts words based on how well you know them, helping you review weak or almost-forgotten terms before they slip away. You can also create your own custom word books for specific goals, and add words from a photo of a textbook or handout. Take a vocabulary level check to measure your current knowledge and select the ideal course for your level. ■ Listen on the go Turn on audio autoplay to listen to your words wherever you are. Adjust audio through 7 speed settings ranging from 0.5x to 3.0x. Background playback keeps audio running smoothly even when your screen is locked.

Speak On.は、英語を「正す」ためのアプリではありません。 あなたの英語を、長く・具体的に話せるようにするスピーキングトレーニングアプリです。 多くの学習者は、文法の正確さに意識が向きすぎて、十分な量を話せていません。 その結果、正しいけれど短文で表面的な内容に終始してしまい、流暢な印象からは離れてしまう。 Speak On.では、細かいミスを気にするのではなく「どれだけ長く具体的に話せるか」にフォーカスすることで、流暢性向上を狙います。 ■ 主な特徴 ・無限に話せるスピーキングトレーニング ・関係代名詞や深掘り要素(理由や目的の表現)など、具体的で実践的な表現力にフォーカスし、それぞれ個別にAI判別・評価 ・AIによるオーバーオールフィードバック(すぐに確認可能) ・スコアと履歴で成長を可視化 ■ こんな方におすすめ ・英語は勉強してきたけど、話せない ・もっと長くスラスラ話せるようになりたい ・いつも短文ですぐに詰まる ・自分の英語に自信が持てない ・実践的なスピーキング力を伸ばしたい Speak On.は、日本人学習者のために設計されています。 「正しい英語」から「長く、具体的な英語」へ。 あなたのスピーキングを一段引き上げます。 Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
