AI Analysis

●●SolidSolve My ProblemShip It

Replaces Flipper with a zero-config floating overlay for React Native performance inside Expo.

Strengths
  • •Uses the Hermes performance.memory API directly instead of requiring native module linking.
  • •Disappears completely in production builds preventing accidental leakage of dev tools.
  • •Draggable dashboard lets see metrics in context without switching debugger windows.
Weaknesses
  • •UI FPS is approximation via Animated timing drift rather than native measurement.
  • •Zero stars GitHub suggests unproven stability compared to established profiling tools.
