Design a Learning App That Works on Zero Data

Mobile data in Nigeria costs real money. Many students top up irregularly, run out mid-lesson, or share a phone with three siblings. The assumption that a learning app requires a permanent internet connection locks out the majority of the students who most need it. Your challenge is to design a learning app — for secondary school students aged 14 to 18 — that delivers a genuinely useful education experience on zero data. Content can be pre-downloaded, delivered via SMS, or use any other approach. The experience must not feel like a compromise. Submit: a product design document including user flow, content delivery mechanism, what the student can do offline vs online, onboarding flow, and at least 5 detailed screen designs or wireframes. Judging criteria: 35% offline experience quality, 30% design and usability, 20% content delivery cleverness, 15% feasibility.
