Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
• Accurate CPU tracking for complex apps — Xcode, Chrome, and other apps with background helper processes (build services, compilers, renderers) now show their true total CPU usage instead of just the main process
• Instant process discovery — all system processes are now detected from launch, delivering accurate CPU readings from the very first second
