Mobile App Developer Needed — Branded Customer App for Independent Supplement Retail Chain

We are Next Level Sports Nutrition, an independent supplement retail chain with multiple locations across Kentucky and Indiana. We've built a loyal customer base over the years and are now ready to take the next step — a branded mobile app that gives our customers a personalized, data-driven experience they can't get from a big-box retailer. We are looking for an experienced mobile app developer (or development team) to build our customer-facing iOS and Android app from the ground up. 🎯 What we're building This is a customer-facing app designed to keep our shoppers engaged, informed, and connected to their health data. Phase 1 features include: • Macro Calculator — a branded, easy-to-use tool for tracking daily nutritional targets • InBody Scan Viewer — customers can log in and view their InBody 270 body composition scan history and results directly in the app • Purchase History — integrated with our Lightspeed POS system so customers can view their order history • Customer Login / Profile — secure account creation and management 🔧 Technical considerations • Cross-platform preferred (React Native or Flutter) — one codebase for iOS and Android • InBody 270 integration — experience with or willingness to research the InBody developer API is important; this is a key differentiator for the app • Lightspeed POS integration — purchase history pull via Lightspeed API • Secure user authentication and data handling — body composition data is sensitive and must be treated accordingly • Scalable architecture to support AI/recommendation features in future phases Phase 2 (future development) will expand into: • Personalized workout plans • Nutrition and eating recommendations • AI-driven supplement suggestions based on individual goals, scan data, and purchase history We want a developer who can build Phase 1 cleanly and with Phase 2 in mind — the architecture needs to support where we're going, not just where we're starting.
