Learn Languages Through Sentence Memorization Memorizing words alone won't help you speak. Studying grammar doesn't guarantee fluency in real conversations. Why? Because you haven't trained your brain to "retrieve" sentences. This app combines flashcard retrieval training with a scientific spaced repetition algorithm to make memorized sentences come out naturally in conversation. ■ Key Features ▸ Flashcard Retrieval Training Practice retrieving sentences from your brain. Memorized sentences will automatically come out in real conversations. ▸ Scientific Spaced Repetition Algorithm (Anki-style) Automatically calculates your optimal study schedule for efficient memorization. Review at the perfect timing based on the forgetting curve. ▸ Choose Your Own Sentences Memorize only the sentences you'll actually use. Build personalized learning decks for your specific needs. ▸ Learning Statistics & Progress Tracking Monitor your learning status with detailed statistics. See at a glance how much you've memorized and retained. ▸ iCloud Sync Study seamlessly across iPhone, iPad, and Mac. Your learning progress syncs automatically across all devices. ▸ CSV File Import Easily import your own learning materials via CSV files. Materials created in Excel or Google Sheets work instantly. ■ Perfect For - Those who know words but can't speak - Those who studied grammar but struggle in real conversations - Anyone who wants to memorize efficiently - Anki users who found it too complex - Learners who want to choose only useful sentences ■ Why Memorize Sentences? Word memorization: "apple" = apple → "I ate an apple" doesn't come out automatically in conversation Sentence memorization: "I ate an apple yesterday" → The entire sentence comes out naturally when the situation arises When you memorize sentences, grammar, word order, and expressions stick together as chunks. This is real speaking ability. ■ What is Spaced Repetition? A method of reviewing at optimal intervals based on the human forgetting curve. - After 1 day → 3 days → 7 days → 14 days... Repeating with increasing intervals converts information into long-term memory. The app automatically calculates "today's review cards," so you just need to open the app and study every day. ■ Start Now Experience memorized sentences coming out naturally. Enjoy the pleasure of efficient memorization through scientific methods. Start now. - Terms of use https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
