Cross-Platform Utility App Development

I need a straightforward utility app built from the ground up for both iOS and Android. The single must-have feature is seamless data synchronization, so users can start a task on one device and pick it up instantly on another without friction. I’m open to the framework you prefer—Flutter, React Native, or Kotlin Multiplatform—so long as the final binaries meet current App Store and Google Play requirements and performance feels fully native. Clean, well-commented source code and basic UI/UX that follows each platform’s guidelines are essential. Deliverables I expect: • Wireframes or mock-ups for approval • Source code in a private repository • Test builds for both platforms • Final release builds ready for store submission • Brief hand-off documentation outlining build steps and sync logic If you can suggest lightweight user authentication or push notifications that won’t bloat the scope, let me know, but they’re not mandatory for this first release. Looking forward to your approach and timeline.
