The gap in language learning apps
Language learning does not lack apps. It lacks a reliable practice system that connects vocabulary, listening, speaking, grammar feedback, and spaced review into visible progress.
Apps reward streaks without proving speaking ability
Speaking and listening checks are tied to your actual level — a scored mock exam, not just a badge for opening the app.
Vocabulary is memorised in isolation
Every word arrives in a full sentence generated around your profile, reviewed on a spaced-repetition schedule (FSRS), and reused in reading, writing, and conversation — not a flashcard in a vacuum.
Grammar corrections do not teach the pattern
Feedback explains the rule that was broken, then asks you to produce a repaired sentence yourself — correction plus retrieval, not just a red underline.
Teachers cannot see daily language practice evidence
A class dashboard shows what each student reviewed, spoke, and got wrong — real evidence, not a self-reported completion checkbox.
See how this compares to the two apps most people already know in Language Ninja vs. Duolingo & Babbel, or the mechanics themselves in how the spaced-repetition scheduling works.
