Course apps that make learning easy to finish.

People return to a course because the next step is obvious. That means a clean course structure, short lesson summaries, progress that is easy to resume and a player that remembers where the learner stopped. If those pieces are weak, more content does not fix completion.

I build the lesson model and progress rules before the screens. That makes it possible to support video, text, downloadable resources and quizzes without each format inventing its own completion logic.

Courses can be sold individually, as a subscription or as a cohort. Each model changes the entitlement rules, the refund path and what the app shows after purchase. I build the server-side checks so a user cannot unlock paid content by changing a local flag.

Live classes add scheduling, reminders, attendance and a call provider. I can integrate 100ms or a similar service, or work with the platform you already use. Offline downloads and DRM are separate decisions with real trade-offs, so we scope them explicitly.

A course product needs an admin surface for courses, lessons, media, coupons, enrollments and support. If every content change needs an app-store release, the product will stall. I build the admin flow alongside the learner app and document who can do what.

Analytics should answer practical questions: where learners stop, which lessons are replayed, which assessments fail and which cohorts need attention. That is more useful than a dashboard full of vanity totals.
