Your day is lighter. Questions you missed now come back in a short review of their own on Home, and each one shows the lesson it came from. "One more?" really means one more lesson. Lessons in the Catalog open to read whenever you like. And close your daily ring to see it turn green and celebrate with you. Also fixed: a lesson you close partway always reopens where you left it.
Noa gives you one thing to learn each day, and then tells you you're finished. A question to open with. One short lesson, a card at a time. A handful of questions to make it stick. About five minutes, and then a real finish line, with no feed to fall into and no reason to keep scrolling. SIX SUBJECTS TO START Astronomy. Compound interest. How memory works. How the internet works. Keeping time. Stoicism. Every lesson is checked by a person before it ships, and every question links to the source it came from, so you can verify it yourself. New subjects arrive in updates. BUILT TO BE KEPT UP Streaks that forgive a missed day instead of punishing it. XP and a rank ladder for each topic you follow. Questions you get wrong come back on a spacing schedule until they stop being questions you get wrong. WORKS WITH NO SIGNAL Everything is on your phone. No account, no email, no sign-up, no ads. Do a session on the train.
