I’m building a focused productivity tool that helps users stay on top of their tasks, and I need it released on both iOS and Android. The cornerstone feature is robust task management—creating, editing, prioritising, and completing tasks must feel effortless and fast. While calendar integration and broader collaboration tools may come later, they are not in scope for this first phase; the entire user journey should revolve around an intuitive, distraction-free task workflow. I’m open to a native build or a solid cross-platform framework such as Flutter or React Native, provided the final experience is smooth, secure, and adheres to current App Store and Google Play guidelines. Clean, well-commented code stored in a private Git repository is essential, and I’d like concise documentation so future features slot in without rework. Deliverables: • Wireframes and UI mock-ups approved before development • Fully functional task-management app for iOS and Android • Source code in a Git repo with setup instructions • Test builds (TestFlight / APK) and a short hand-off guide If you have shipped productivity apps before and can walk me through your approach to performance, offline handling, and simple yet elegant UX, let’s talk timing and milestones.
