PROBLEM
Language apps assume a connection. Practice happens on commutes, in transit and in dead zones — exactly where a network-dependent app stops being usable.
APPROACH
Structured roadmaps per language over a flashcard and audio core, delivered as an installable PWA that keeps working offline and saves progress locally until it can sync.
OUTCOME
Live, with lessons, audio and roadmaps available offline and progress preserved through connection drops.
