FitTrack AI — iOS & Android Fitness Coaching App

FitTrack had a basic fitness app with static workout libraries. Users dropped off within 2 weeks because plans weren't personalised. They needed AI-generated adaptive plans that evolved with a user's progress, plus social features to improve retention.

We rebuilt the app in React Native for code-sharing across iOS and Android. A Python ML service ingests user biometric data, workout history, and feedback to generate weekly plans using a fine-tuned LLM. Gamification (streaks, badges, challenges) and social sharing features were added to boost DAU. A real-time video analysis module uses the device camera to check exercise form.
