I need a skilled developer or small team that can take my concept for a mobile music-focused application and turn it into polished, production-ready builds for both iOS and Android. Because I intend to launch on the App Store and Google Play simultaneously, I’m open to cross-platform frameworks such as Flutter or React Native, but I’m happy to hear recommendations if you feel a fully native route is the better long-term choice. Core expectations • End-to-end development: wireframes (I can supply basic sketches), UI implementation, feature coding, testing and store submission • Clean, well-documented source code that I can continue to iterate on after launch • Regular test builds so I can validate functionality on real devices throughout the process Acceptance criteria 1. Compiles and runs smoothly on current iOS and Android versions 2. Passes App Store/Play Store review guidelines for a music category app 3. Delivered with full source code, build instructions and final binaries (IPA & APK/AAB) If you have shipped music, audio or media apps before, please link them—those examples will weigh heavily in my decision.
