I plan to launch a polished mobile application that mirrors the overall experience and quality found on https://flo.health/. The project covers both iOS and Android, so I’ll need one code-base that runs smoothly on each platform—or two native builds if that proves the better route for performance. High-level scope The core idea is a women’s health companion with an intuitive, data-driven interface. Design, UX flow, animations, and data security should feel every bit as refined as the reference app. Exact feature depth (cycle tracking, personalised insights, community spaces, etc.) will be finalised together once we map the product roadmap. Key expectations • Complete design system that respects modern platform guidelines while keeping a cohesive brand look. • Reliable mobile architecture, clean code, and full testing coverage. • GDPR-grade data protection and encryption for sensitive health information. • Analytics hooks so I can track engagement and retention from day one. • Store-ready deliverables, plus clear hand-off documentation and source code. Acceptance criteria — Both iOS (App Store build) and Android (Google Play build) pass review with no critical issues. — Screen-to-screen navigation, event tracking, and background sync behave identically to the prototype/wireframes we approve. — All user data is stored and transmitted securely using best-practice encryption. — I receive full, un-obfuscated source code and a walkthrough of the build pipeline. Preferred tools & stack Swift UI or Kotlin if we go native; Flutter or React Native if cross-platform offers a better balance of speed and cost. I’m open to your recommendation as long as performance and long-term maintainability stay front and centre. Timeline Once we lock the final feature list, I’d like to move quickly into sprints and aim for a store launch within a mutually agreed schedule. Share any similar health-tech apps you’ve released, describe your proposed tech stack, and outline how you’ll handle secure data workflows, and we can start the conversation from there.
