A lesson, then a puzzle, then a game — and a teacher who can see exactly where the class is. Mistakes are safe here.
Android builds go to invited testers through Firebase App Distribution.
For children
Read the theory, keep the key facts, then answer the chapter's puzzles. The next lesson only opens when this one is done.
A puzzle bank per chapter across three levels — Skill, Knowledge, Wisdom. Getting it wrong just means another try.
The reward room: pawn races, speed chess, the daily puzzle, and the class leaderboard — unlocked chapter by chapter.
For teachers & parents
Every child × every concept, coloured by mastery: mastered, in progress, or stuck. It is computed from the puzzles they actually attempted — no self-reporting, no guesswork.
Class overview · full grid · individual student · concept analytics
The teacher shares a private link and the family sees a weekly summary in plain language. No password, no app to install, and the teacher can revoke it any time.
Children sign in the same way — a link from their teacher, never a password.
Open the web app and pick “Student” — no sign-up needed to look around.
