Educational apps that actually teach
Interactive explainers, typing trainers, subject tutors, flashcard apps, and simulations designed for curious people rather than course-completion metrics. Each one runs in your browser, so there's no LMS login, no textbook rental, no paywall mid-lesson — just the thing you came to learn.
A geography speed-quiz. Type country names against the clock — every one you nail lights up the map. Eight maps (world + every continent), three paces, leaderboards, percentile standings, and a per-answer rarity stat that shows how many other players named each country.

A world-capitals speed quiz. You’re prompted one country at a time — type its capital and the country fills in with a pin dropped on the real city; hit Reveal if you’re stuck (it won’t count). A spotlight panel zooms to show you where the asked country is while the full map stays put for context. Eight maps (world + every continent), three paces, leaderboards, percentile standings, and a per-answer rarity stat that shows how many other players knew each capital.
