Cross-Platform Marketing Mobile App

I’m looking for a developer who can take my idea for a marketing-focused mobile application and turn it into a polished, production-ready product that runs smoothly on both iOS and Android from a single codebase. A cross-platform framework such as Flutter or React Native is ideal, but if you have a better suggestion I’m happy to discuss it.

Here’s what I need:
• Plan and build the entire app—UX, UI and core functionality—around the goal of helping users execute, track or optimise their marketing efforts.
• Ensure seamless performance and a consistent look and feel across devices.
• Implement analytics so user behaviour and campaign results can be measured accurately.
• Prepare the builds for both App Store and Google Play submission, including any required certificates and store assets.

If you can show prior experience shipping cross-platform apps—especially those with a marketing angle—let’s talk through your approach, estimated timeline and any questions you have about scope.
