I’m ready to bring a new subscription-based product to market and need the full stack of apps built in tandem: a responsive web application and matching mobile apps for both iOS and Android. Users will sign up, manage their plan, and access gated content or features through a single account, so the experience must feel seamless no matter which device they pick up. You’re free to recommend your preferred toolkit—whether that’s React Native, Flutter, Swift/Kotlin paired with a REST or GraphQL backend, or another modern approach—as long as the final result is reliable, secure, and easy to maintain. Clean, well-commented code and straightforward deployment instructions are essential because my in-house team will take over day-to-day updates once we launch. Deliverables I’ll review at hand-off: • A production-ready web app, responsive on all major browsers • Fully tested iOS and Android builds published (or ready to publish) to their respective stores • All source code, environment files, and a brief README covering setup, build, and deployment steps If the stack you propose supports a shared codebase across web and mobile, that’s a plus—but I’m most concerned with performance and a polished user experience. Let me know how you like to structure milestones and what you’ll need from me (API keys, design assets, etc.) to move quickly.
