Score: 7.5/10 (Innovation: 7, Technical: 6, Documentation: 9, Utility: 8)

A floating performance overlay for React Native that shows real-time metrics like FPS, memory, re-renders, and network activity directly on screen. It's interesting because it fills a gap left by Flipper's removal in React Native 0.73+ with a zero-config, production-safe tool that requires no native modules.

Target audience: mobile developers, react-native developers, frontend devs
