Seek is a React Native mobile application for identifying plants, animals, and fungi using the device camera and on-device machine learning (InatVision). It allows users to capture photos, receive species identifications, save observations locally via Realm, and optionally post them to the iNaturalist citizen science platform. The app includes gamification features such as badges, levels, monthly challenges, and a year-in-review recap. It integrates with iNaturalist APIs for authentication, species data, range maps, and seasonality charts. The architecture is a monolithic React Native app with multiple Context providers for state management, React Navigation for routing, and a variety of native modules. The codebase is well-structured with TypeScript, has CI/CD pipelines, and uses snapshot tests. However, it has technical drift from patched dependencies, hardcoded monthly challenge content, and some tightly coupled components. Overall, it is a solid, actively maintained mobile app with moderate reusability of its UI primitives and custom hooks.
