I’m looking to turn my productivity concept into a polished mobile app that runs smoothly on both iOS and Android. The goal is to help users organize tasks, set reminders, and track progress in a clean, intuitive interface. Here’s what I need: • A cross-platform codebase (React Native, Flutter, or a comparable framework) compiled for the App Store and Google Play. • Core features: task creation, due-date reminders (push notifications), basic analytics or progress charts, and secure user accounts with email or social login. • A straightforward onboarding flow and a minimal, distraction-free UI that adapts to dark/light mode. • Source code in a private Git repository, plus build instructions so I can replicate releases. I’ll provide initial wireframes and a feature priority list once we start. Please factor in iterative feedback rounds and include any relevant portfolio links so I can gauge your experience delivering productivity tools on both platforms.
