I need a mobile application whose single focus is to guide users through physiotherapy exercises by video. Every exercise will have two viewing options: a pre-recorded tutorial they can replay any time and, where required, a button that drops them straight into a live session with a therapist. Because the videos sit at the heart of the product, smooth playback and crystal-clear streaming matter more to me than an overload of extra features. A clean interface that lets users filter exercises by body part or injury, mark favourites, and see what they completed last time will be enough for version 1. Key deliverables • Cross-platform mobile app (iOS & Android) built in React Native or Flutter – whichever you are fastest with • Secure upload/storage for pre-recorded clips, plus an in-app player with scrubbing, speed control, and offline caching • Live session module (WebRTC or similar) that supports therapist cam, basic chat, and automatic push notification reminders • Lightweight admin panel so I can create exercise categories, attach videos, and schedule lives without touching code • Source code, build instructions, and a short hand-over call to walk me through deployment If you have shipped an app that combines recorded content with live streaming, your experience will fit perfectly. I’m happy to adapt to the hosting stack you prefer as long as it scales and shields the streams behind secure authentication. Let’s keep the project tightly scoped, get the core workout flow working first, and we can talk add-ons like progress analytics in a later phase.
