Cross-Platform Productivity App Build

I’m planning a new mobile productivity app and need someone who can take it from concept to launch on both iOS and Android. At this stage the core idea is defined, but the exact feature set and visual style are still flexible, so I’m looking for a developer who can actively collaborate on refining requirements, proposing UX flows, and selecting the most suitable tech stack—whether that’s Flutter, React Native, native Swift / Kotlin, or another modern solution you’re comfortable with.

Key things I’d like covered:
• Full-cycle development: wireframes, UI design, front-end and back-end coding, testing, and store deployment.
• Clean, well-documented source code handed over through Git.
• A build that runs smoothly on recent versions of both iOS and Android without platform-specific quirks.

There’s no hard deadline, so quality and thoughtful iteration matter more than rushing features out the door. If you have past examples of productivity apps—or any cross-platform projects that show strong UX and reliable performance—include them with your proposal along with a quick outline of how you’d approach version 1.0.

Looking forward to building something great together.
