The user problem
Learning tools need to hold a child’s attention while giving parents understandable progress. A collection of lessons alone does not connect practice, engagement and follow-up.
Product decisions
Connect quizzes, read-aloud stories, math games and voice practice in one learning experience. Keep parental progress visible and use age-appropriate activities. Publishing and distribution are described only where there is a public entry point.
Engineering trade-offs
Next.js supports interactive web journeys and authentication. Firebase provides an integrated backend, offline persistence and notification capabilities. Domain, game and API boundaries keep learning rules separate from presentation and transport.
What exists today
The public learning website includes an Android download entry point.
