WatchdogInspector
A debugging tool that displays real-time framerate (fps) and detects main thread stalls in iOS apps via the status bar.
What is WatchdogInspector?
WatchdogInspector is an iOS debugging tool that displays the app's current framerate (fps) in the status bar and detects main thread stalls. It helps developers identify performance issues that cause UI lag by providing real-time visual feedback and optional exception throwing for blocked threads.
iOS developers and mobile engineers who need to monitor and optimize app performance, particularly those working on apps requiring smooth animations and responsive interfaces.
Developers choose WatchdogInspector for its non-intrusive, real-time performance monitoring directly in the status bar, eliminating the need for external profiling tools during development and enabling quick identification of framerate drops and main thread blocks.
