Fitty Friends

Summary

Fitty Friends is an innovative iOS fitness app developed at HackMIT that gamifies personal fitness through AI-powered virtual pets. The app allows users to create and interact with personalized virtual pets that respond to their fitness activities, creating an engaging and motivating fitness experience. Users can feed their pets by tapping interactive elements, collect different pet types, customize their appearance, and track their fitness progress through integrated wearable device data. The app features a comprehensive backend system that processes fitness data from multiple wearable providers (Garmin, Oura, Google, Fitbit) via TerraAPI, generates personalized AI-driven notifications, and creates unique pet personalities using DALL-E 2 image generation. The modular architecture includes a React Native frontend with navigation between home, collection, shop, challenges, and profile screens, while the FastAPI backend handles data processing, pet management, and AI integration.
