iOS & Android App Creation

I am planning a professional mobile app that must run seamlessly on both iOS and Android from the very first release. The core build has three non-negotiable features: secure user authentication, reliable in-app purchases, and real-time push notifications. For the interface, I want a balanced mix—eye-catching custom screens where brand impact matters, supported by the standard UI elements users already know and trust. I’m happy to discuss whether you prefer Flutter, React Native, Kotlin/Swift, or another approach, as long as performance and store compliance remain top priorities. Deliverables I expect • Full source code with clear documentation • Tested builds ready for App Store and Google Play submission • Basic post-launch support to iron out any critical bugs If this scope aligns with your expertise, let’s talk through milestones and start dates.
