Hello, With 17+ years of development experience, I have extensive experience building and launching cross-platform mobile applications. For this project, I recommend Flutter for a shared Android/iOS codebase, with REST APIs for integration, secure authentication for user accounts, and a scalable local data layer for reliable synchronization. My approach: * Design a clean, intuitive utility-focused UI and implement the required account management flows. * Integrate APIs and build reliable data synchronization with proper loading, error and offline-state handling. * Perform functional/device testing, optimize performance, and prepare the application for Google Play Store and App Store submission. * Provide clean, maintainable source code and support during deployment. I can start quickly and structure the work around your ₹12,500–₹37,500 budget, depending on the final feature/API scope. Looking forward for connecting. Best Regards, Nisha

@nathanholmes

Your requirement for one developer to take a utility app from UI/UX through API integration, testing, and both store deployments makes having a consistent technical approach important from the beginning. The main challenge will be keeping account management and data synchronisation reliable across Android and iOS while maintaining a simple utility-focused experience. I’d use a cross-platform architecture to keep the two builds aligned, with secure authentication, efficient API integration, reliable data sync, responsive UI, and thorough testing across common devices. I’d also handle the store-ready builds and deployment process, with clear documentation for future maintenance. I have hands-on experience with mobile app development, UI/UX, APIs, authentication, data synchronisation, testing, and app deployment. Open to discussing the utility’s core workflow and preferred stack.

@WOFZahid

Hi, I can build this app for both iOS and Android. I have 9 years of mobile and full-stack experience, and I've worked on utility apps with user authentication and real-time data sync. Before I scope this, I need to clarify one thing: Do you have a preference between native development (separate iOS and Android codebases) or cross-platform (one codebase, faster delivery, lower cost)? I recommend React Native with Expo—it's production-ready for both platforms and deploys to both app stores in days, not months. I also need to understand the data sync requirements. What data needs to sync? How often? Does the app need to work offline? What APIs will it connect to? These details will help me give you an accurate timeline and approach. While I don't have a public mobile app listed yet, I'm happy to share screenshots and a working demo of previous utility apps I've built in our chat to show the quality of my work. Looking forward to discussing this.

@Mayanks010

Hi, Thanks for sharing your project. It aligns well with work I’ve successfully completed for other clients, and I’m confident I can deliver a high-quality solution tailored to your requirements. Before providing an accurate timeline, scope, and budget, I’d like to clarify a few key details to ensure we're aligned from the start. Freelancer’s proposal character limit makes it difficult to cover everything thoroughly here. If you're available, let's connect via chat. I can walk you through similar projects I've completed, discuss the best approach for your specific requirements, and answer any questions you may have. Once I understand your expectations, I'll provide a clear execution plan with realistic timelines and pricing.
