How it works
Local-first learning with a controlled content pipeline.
02
Unlock mastery depth.
Paid one-time packs unlock Difficulty 5-6 depth for launch flagships: DSA, CS Math, and Developer Systems.
03
Keep the app resilient.
A bundled fallback works offline, while the curriculum CDN lets vetted lesson fixes ship without a full app review.
