I want to bring reading and gaming together in one slick, modern experience that works everywhere—native on iOS and Android, plus a responsive Web version. The catalogue will launch with e-books and comics, and every page a user turns should feel like progress in a game. Core mechanics • Achievements & Badges unlock automatically as milestones are hit (pages read, streaks, series completed). • Leaderboards show individual and community progress in real time. • A Rewards System pays out in-app coins that users can later redeem; the earning flow must be friction-less and secure. Experience & tech expectations The interface needs to feel fast and immersive, with smooth page transitions, dark/light themes, and offline reading. A shared backend should keep progress synced across all three platforms, handle gamification logic, and expose a simple admin console where I can upload new titles, create special badge campaigns, or adjust reward ratios without touching code. Deliverables • iOS, Android, and Web landing page ready for store/production release • Scalable backend with API documentation • Admin console with role-based access • Source code, build instructions, and a short hand-off walkthrough Acceptance criteria 1. A new reader can sign up, pick a comic or book, read offline, come back online, and see coins appear immediately. 2. Completing any title triggers a badge and updates the global leaderboard in under five seconds. 3. All three clients share the same user state without data loss or duplication. If you’ve built cross-platform apps with deep gamification layers before, let’s talk about timelines and your preferred stack so we can get this into readers’ hands soon.
