Diagnosis

Specific, not generic

Generic tools say "your app is slow." Reinpl says "CartItem on /checkout re-renders 47× per session - wrap with React.memo."

📊
Actionable score

Weighted Performance Index

WPI scores your app 0–100 across render duration, re-render frequency, blocking renders, and trend. One number, total clarity.
