I have an interactive web prototype for SafeZen—my startup that boosts cognitive performance through quick reaction-time tests and guided focus sessions—and I’m ready to turn it into a polished mobile MVP for both Android and iOS. The feel I’m after is unmistakably minimalist: clean screens, friction-free navigation and zero visual clutter. Core user flow is already validated on the web; your job is to recreate that experience natively (or with a robust cross-platform stack) while keeping the door open for future feature growth. Key functions that must ship: • Reaction-time focus test that runs smoothly on a touchscreen • Pre-recorded guided audio focus session (no user uploads in this phase) • Automatic before/after measurement and focus-score calculation • Progress tracking with clear, lightweight charts • Email-and-password sign-up / sign-in I’ll supply Figma frames, component guidelines, and the working web code so you can mirror the logic and APIs. Build architecture with scalability in mind—modular code, clean state management, and sensible data storage—so we can later add more session types or social logins without a full rewrite. Deliverables 1. Production-ready Android and iOS builds (store-compatible) 2. Source code in a Git repo with clear README 3. Brief hand-off document covering setup, third-party libraries, and next-step recommendations Acceptance criteria • UI follows the provided minimalist style and passes basic accessibility checks • All five core features work offline once content is cached • Cold start to test screen under three seconds on mid-range devices • No critical errors in Firebase/Crashlytics (or your equivalent) during a two-day test window If you’ve shipped comparable apps—especially ones with reaction games, charts, or audio playback—let me know. Looking forward to collaborating and bringing SafeZen to pocket-sized life.
