I manage a basketball academy and need a mobile app that works flawlessly on both iOS and Android. Its primary job is to maintain up-to-date student records and fee details while also giving players a convenient in-app shop for essentials such as uniforms and training gear. Key features for the first release: • Secure login for students, parents, and coaches • Student profile management with attendance and performance notes • Real-time fee dashboard with due dates, partial payments, and automated reminders • Simple product catalog, stock tracking, and purchase or reservation flow tied to each student account • Push notifications for overdue fees and new product drops • Exportable reports (CSV/PDF) for monthly finance reviews I’m comfortable with any modern stack—Flutter, React Native, or a native Swift/Kotlin split—so long as it delivers a maintainable, cross-platform codebase. Because I need this ASAP, please include a detailed project proposal outlining architecture, milestones, and a timeline that shows how quickly you can deliver an MVP and iterate to full release. I’m available daily for rapid feedback and expect a tight, efficient development cycle.
