I want to bring a straightforward, classroom-style quiz experience to both iOS and Android, but I have absolutely no development background, so the project has to cover everything—planning, coding, testing, store submission and post-launch hand-holding. The core of the app is a bank of multiple-choice questions that I can keep expanding on my own. All content will sit behind a simple class selector (implemented as a drop-down menu) so students pick their level the moment they open the app. Home screen • Upper section: a live leaderboard that automatically shows the top-10 scorers for the selected class. • Lower section: a personal progress bar per subject—Math, English, Science and Malay language—displaying something like “100 / 1 000 questions answered”. Essential features I need built in – Intuitive template or admin panel where I can upload or bulk-import new multiple-choice questions any time without touching code. – Cloud-based storage so rankings and progress sync across devices. – Clean UI that makes the drop-down class selection obvious and the progress bars easy to understand. – End-to-end publishing: certificates, screenshots, store listing text, TestFlight / Play Console testing, final submission and acceptance. After hand-off I expect clear documentation (video or PDF) on how to add questions, reset leaderboards and push app updates. Code ownership remains with me and the finished builds must pass App Store & Play Store review. If this fits your skill set, please include a quick outline of the tech stack you recommend (for example Flutter + Firebase or React Native + Supabase) and an estimated timeline from kick-off to store approval.
