A speaking-focused English conversation app! Many language apps offer passive speaking practice or no feedback at all. Even in English conversation schools, learners often rely on familiar expressions and struggle to acquire new words, phrases, or idioms. This app is different — it encourages active speaking, provides AI-based scoring, and suggests more natural and advanced expressions! The large language model (LLM) behind the app offers rich, native-level (or even better) suggestions to elevate your English. Includes over 2,000 questions, with new content added regularly. Questions cover various real-life scenarios including daily conversation and business. Just one question a day is enough to make real progress! The app uses a ticket-based system instead of a subscription. You can purchase tickets based on how much you want to train. No ads included!

意志が弱いんじゃない。逃げ場が、あるだけだ。 Kusariは、毎日の英語学習を「鎖」で習慣に変えるアプリです。読む、話すの2ステップ、1日15分ほど。意志の力ではなく、設計で続けます。 コミットメント・デバイス(自分への約束を仕組みで守る装置)の研究をもとに設計しています。Yaleの研究者らが立ち上げたstickKなどで知られる手法です。Kusariは同大学と提携・監修関係にはありません。 料金は、続けた日数で決まります。 通常価格 月¥5,000(自動更新)。直近30日の達成日数によって、翌月のご請求が5段階で変わります。 ・24日以上 ¥0 ・18〜23日 ¥1,000 ・12〜17日 ¥2,500 ・6〜11日 ¥4,000 ・5日以下 ¥5,000(通常価格) 日数に比例して安くなるのではなく、上の5段階で決まります。 割引の適用には、更新日の前にアプリ内で申請の操作が必要です(Appleの仕様上、自動では適用できません)。アプリが更新前にお知らせします。 最初の7日間は、登録なしでお試しいただけます。8日目にご登録いただくと、そこから30日間の無料トライアル(初回のみ)が始まり、最初のご請求はその後です。 お試し期間7日分の記録は、ご登録後のアカウントには引き継がれません。 サブスクリプションは自動更新です。期間終了の24時間前までに、iPhoneの「設定」>ご自身のApple ID>サブスクリプションから解約できます。 今は三日坊主でも大丈夫です。続けられる自分に変わるための仕組みだけ、用意しました。
