Cross-Platform Mobile App Build

I need an appointment mobile application produced for both iOS and Android from the same code-base. Native Swift/Kotlin, Flutter, or React Native are all acceptable—what matters most is a smooth, reliable user experience on each platform.

Once an NDA is in place I’ll share the feature set, wireframes, and user-flow notes; you will then handle the build, testing, and store release.

Deliverables
1. Complete, well-commented source code.
2. Test builds that run on the latest iOS and Android versions.
3. App Store and Google Play–ready binaries, including screenshots, icons, and compliance assets.

Acceptance criteria
• Compiles without errors in current Xcode and Android Studio.
• No critical/high bugs after one week of user testing.
• Approved and live in both stores.

Please attach links to apps you’ve shipped on both platforms and outline the stack you propose along with an estimated milestone schedule.
