I’m ready to move my high-yield investment program onto a dedicated mobile platform and need a full-featured app that runs smoothly on both iOS and Android. The core of the project is twofold: • Investment tracking – investors must see live performance data, historical yields, pending payouts, deposits and withdrawals in a clean, real-time dashboard. • User account management – seamless sign-up, KYC/verification, secure login, profile editing, two-factor authentication and an in-app support channel. You’re free to choose the most efficient cross-platform framework (Flutter, React Native or similar) as long as the final builds feel fully native, pass App Store and Google Play reviews, and are easy to maintain. REST/GraphQL skills are essential because the app will consume my existing backend APIs; if you can help refine or extend those endpoints, even better. Security is non-negotiable: AES-256 encrypted storage, HTTPS/TLS everywhere, and clean, well-commented code that stands up to an external audit. A thoughtful, modern UI that guides new investors yet doesn’t overwhelm experienced ones will earn extra points. Deliverables 1. Production-ready iOS and Android app binaries plus all source code. 2. Integration with my backend (API keys supplied after kickoff). 3. Unit and integration test suite with coverage reports. 4. Release-ready store assets (screenshots, icons, descriptions). 5. Short hand-off guide so my in-house team can take over routine updates. Acceptance Criteria • Both apps install and run without crashes on the latest two OS versions. • Portfolio data refreshes in <2 seconds on a standard 4G connection. • All critical paths (sign-up, deposit, withdrawal) covered by automated tests. • Source builds successfully on a clean machine using the instructions you provide. Phase-two features such as market analysis tools can follow once the foundations above are solid. Let me know your preferred stack, any similar finance projects you’ve shipped, and a realistic timeline to hit an MVP and full launch.

Hello, I understand you're looking to transition your high-yield investment program into a mobile app that functions seamlessly on both iOS and Android platforms. This is an exciting and important step for engaging more users efficiently. To achieve this, we can leverage Flutter for cross-platform development, which ensures consistent performance and a cohesive look across devices. I'll utilize GraphQL for efficient data fetching, ensuring that your app remains fast and responsive, even under heavy loads. For the server-side needs, PHP can be employed to create robust APIs, complemented by REST APIs for seamless communication between the app and your backend systems. My focus will be on delivering a user-friendly interface that is intuitive and secure, prioritizing key features such as real-time updates on investment performances, easy fund transfers, and personalized notifications. Rest assured, attention to detail will be at the forefront to craft an experience that caters exactly to your audience’s needs. Best Regards, Khorshed Alam, RS Software

Hi, I will build your high-yield investment app with the real-time dashboard (live yields, payouts, deposits, withdrawals) and full account management including KYC and 2FA, deployed to both App Store and Google Play. On a recent finance app, keeping portfolio refresh under 1.5 seconds on 4G required careful API response shaping, so I will audit your existing endpoints early and flag any changes needed. Questions: 1) Is your backend already handling KYC verification, or will that logic need to be built into the app layer? 2) Do you have UI designs or wireframes, or will I handle the full interface design? Share your API docs and I will map out the MVP screen list this week. Best regards, Kamran
