Designed for Permanent Retention

Traditional language apps teach you words once and hope you remember. LinguaCue schedules reviews right at the critical moment before memory decay.

⚡

FSRS Memory Algorithm

Free Spaced Repetition Scheduler tracks your memory stability and difficulty per card, predicting the exact optimal review interval for 90%+ retention.

🎙️

Immersive Native Audio

Every single vocabulary word and example sentence comes with crystal-clear native audio pronunciations, pitch accents, and phonetic stress cues.

🎯

Real-World TBLT Missions

Put words to work in Task-Based Language Teaching missions — order coffee in Tokyo, navigate trains in Madrid, or book a room in Munich.

🔍

Never wonder why a sentence is phrased that way. Tap into particle explanations, nuance notes, and full stroke-order kanji details.
