The challenge

Students learn on buses and in basements — anywhere but a perfect connection. The app had to feel instant with or without signal.

What we built

An offline-first learning companion with an adaptive spaced-repetition engine, gentle gamification, and seamless sync when the network returns.

The outcome

A 4.8-star rating, a third more weekly active learners, and zero complaints about losing progress underground.
