I’m ready to move my idea from notes and wireframes into a working mobile product that lives in both the Google Play and Apple App Store. Because the concept is still being refined, I’m looking for someone who can guide the entire process—from choosing the right tech stack (native Kotlin/Swift, Flutter, React Native, or another option you recommend) through to final store submission. Here’s what I already know I’ll need: • Two fully functioning apps that share a single codebase where practical, yet still feel perfectly at home on their respective platforms. • A clean, modern interface and smooth onboarding flow; whether you build the UI from scratch or adapt an off-the-shelf kit is up for discussion as long as it looks polished and performs well. • Core features such as secure user authentication, push notifications, and the ability to add revenue streams (subscriptions or one-off in-app purchases) once the initial release is stable. What I’ll supply: – Brand guidelines, basic user stories, and API documentation for the existing backend. – Quick feedback loops and fast decisions so you’re never waiting on me. What I expect from you: – A realistic timeline with milestones, a clear testing strategy, and store-ready builds at the end. – Source code ownership transferred on each paid milestone, with concise documentation so any developer can pick it up later. – Ongoing advice on best practices for performance, accessibility, and future feature expansion. If you have shipped cross-platform apps before, can point to live examples, and are comfortable collaborating on product direction as well as code, I’d love to hear how you’d approach this build.
