I want to build a sleek, reliable productivity app that runs on both iOS and Android. The concept centres on helping users organise tasks, set smart reminders, and track daily progress through an intuitive, minimalist interface. Wireframes for the core screens are ready, along with a concise feature map; your role is to translate these ideas into polished UI/UX and scalable code. Flutter or React Native feel like strong fits, yet I’m happy to hear another cross-platform suggestion if it shortens build time without sacrificing quality. Deliverables • A fully functional MVP deployed to TestFlight and Google Play’s internal testing track • Source code in a Git repo, cleanly structured and commented • Cloud-based back end (Firebase or similar) covering authentication, push notifications, and real-time data sync • Short hand-over guide plus a live walk-through I aim to see the first production build within six weeks and can iterate together after early user feedback. When you reply, please show one or two comparable apps you’ve shipped, your preferred tech stack, and a milestone breakdown so we can kick things off smoothly.
