I need a polished business app that can be published on both Google Play and Apple’s App Store. Its core purpose is accounting and finance, so the build must let users record expenses on-the-go, generate and send invoices, and pull clear financial reports—everything in one place. From the first launch, the workflow should feel intuitive: add an expense in seconds, create branded invoices from stored client data, and view real-time summaries or period-based reports. Data has to sync seamlessly between Android and iOS so users can switch devices without losing a beat. I’m open to the toolset—whether you prefer Flutter, React Native, Swift + Kotlin, or another framework—as long as the final binaries meet store guidelines and pass review. I will provide branding assets and any copy; you handle UI/UX, secure data storage, API integration (if needed), and testing. Deliverables • Source code with clear README for local build • Production-ready APK and IPA (or TestFlight build) • Brief hand-off guide explaining release steps and how to update expense, invoice, and reporting modules I’ll review against the feature list above, app stability, and store-submission readiness before sign-off.
