Physio Exercise Tracking App

I’m a practicing physiotherapist and I want to turn my exercise programmes into a dedicated mobile app that guides clients through each movement and records their progress. The heart of the build is a clear, easy-to-follow exercise library with step-by-step cues (text, photo or video), automatic rep/hold timers, and a simple dashboard that shows how a client is improving over time.

Although the primary focus is guidance and tracking, I also need secure in-app payment processing so clients can pay for one-off sessions or subscribe to premium exercise plans without leaving the app. I don’t need a full booking calendar right now; just the payment flow that can scale later if we decide to add scheduling features.

Key deliverables
• Cross-platform mobile app (iOS and Android) built with a modern framework such as Flutter or React Native
• Exercise-guidance module: searchable library, progression logic, basic form-check prompts
• Tracking module: logs sets, reps, pain scores, and auto-generates progress charts I can view from an admin screen
• Integrated payment gateway (Stripe, PayPal or similar) with receipt handling and basic subscription logic
• Clean, accessible UI that matches my clinic branding and is easy for clients of all ages to navigate

I’ll supply all exercise content and branding assets; you’ll handle architecture, coding, and publishing. Please include examples of previous health-oriented or fitness apps you’ve shipped, note any relevant compliance experience (GDPR, HIPAA, etc.), and outline your estimated timeline from kick-off to app-store release.
