Cross-Platform Productivity App Build

I need a complete end-to-end build of a productivity-focused mobile application that runs smoothly on both iOS and Android. The project scope includes architecture planning, intuitive UI/UX design, clean and maintainable code, thorough testing, and deployment to the App Store and Google Play. A single code-base framework such as Flutter or React Native is welcome if it keeps long-term maintenance efficient, yet I’m open to separate native builds if they yield better performance—feel free to recommend the most appropriate approach after reviewing the requirements with me. Core functionality will center on streamlining daily productivity tasks; once we connect, I’ll share the detailed feature list, wireframes, and any necessary APIs. Deliverables • Fully functional iOS and Android apps meeting the agreed feature set • Source code with clear inline documentation • Brief setup/run guide and a test report covering major user flows • Assistance through the first live release on both stores Acceptance criteria will be finalised together so we both have a clear definition of “done.” Code quality, responsiveness, and store-ready compliance are critical to sign-off. Let’s create a polished, reliable productivity tool that users can rely on every day.
