Mobile App for Personal Training Studio

Full Stack Developer Needed – Build a Health & Fitness SaaS Platform (Long-term Collaboration) About the project We are looking for an experienced Full Stack Developer (or a small development team) to become our long-term technology partner. This is not another fitness app. We are building a digital health care platform for clients of our personal training and physiotherapy studio. The goal is to create a premium product that supports clients every day—not only during training sessions. The project will start as an MVP and will be developed continuously over time. ⸻ Main features (MVP) Client Dashboard A personalized home screen showing: * today’s nutrition summary * upcoming appointments * latest progress * messages from the coach * recently added health documents * recommended educational content ⸻ Nutrition * recipe database * calorie & macro calculator * daily meal planner * nutrition summary * shopping list (optional) ⸻ Progress Tracking * weight history * body measurements * progress photos * personal records * charts and graphs ⸻ Health Records Clients can upload PDF documents such as: * blood test results * MRI * X-rays * ultrasound reports * medical recommendations Documents should be stored chronologically and accessible to assigned specialists. ⸻ Knowledge Center Educational content library containing: * videos * PDF guides * webinars * podcasts Categories include: * nutrition * stretching * mobility * physiotherapy * posture * healthy habits * recovery Search and filtering functionality is required. ⸻ Messaging Private communication between clients and specialists. Support for: * text * images * videos * PDF files ⸻ Community Private social feed where members can: * create posts * upload photos * comment * like posts ⸻ Calendar Integration We currently use Calendesk. The platform should integrate with Calendesk API (if available). Preferred functionality: * Single Sign-On (same login as Calendesk) * appointment synchronization * view upcoming appointments * reschedule via Calendesk We do not need to build our own booking system. ⸻ CRM for Specialists The system should include an internal CRM where coaches, physiotherapists and dietitians can see: * client profile * goals * health history * uploaded documents * progress * appointment history * communication history * internal notes ⸻ User Roles * Client * Personal Trainer * Physiotherapist * Dietitian * Administrator Each role should have different permissions. ⸻ Technology We’re open to suggestions. Preferred stack: * React / Next.js * TypeScript * Supabase (or Firebase) * PostgreSQL * Tailwind CSS The backend should be prepared for a future mobile application. ⸻ We’re looking for someone who: * has experience building SaaS products * has built CRM/dashboard systems before * thinks like a product developer, not only a programmer * communicates well in English * is interested in long-term cooperation ⸻ Please include in your proposal: * links to similar SaaS products you’ve built * your suggested technology stack * estimated budget for the MVP * estimated timeline * your biggest concern about this project (we appreciate honest feedback) We are looking for a long-term technology partner rather than someone who simply completes a one-time project.
