React Native Developer — Health & Wellness Mobile App (iOS & Android)

We are looking for an experienced React Native developer to build Airway Formula — a mobile wellness app for patients undergoing palate expansion treatment (MARPE, FME, MSE). The app includes a daily exercise program with embedded video, an expansion turn tracker with push notifications, symptom self-check with trend graphs, streak and compliance tracking, a personal photo log, a static education library, and a treatment timeline. Full project brief is attached. This is a fixed-price, milestone-based engagement with a budget of $1–$4,000. You must have at least one React Native app live in the App Store, prior Firebase and RevenueCat experience, and have strong UI/UX design capability. We will provide general layout direction and wireframes in Figma, but we are looking for a developer who can take that foundation and deliver a polished, professional aesthetic with proper app flow — think Apple Health meets Headspace. Full source code ownership transfers to the client at project completion. If this sounds like a fit, please read the attached brief carefully before submitting your proposal — we will only respond to proposals that address the specific questions outlined in Section 08.
