IDTracer

About
iDTracer is a port of DTrace, a comprehensive dynamic tracing framework by Sun Microsystems for troubleshooting kernel and application problems, to iOS. The tool was discovered in the filesystem of an iPhone 6S SwitchBoard.app build and can run in SpringBoard. The app also works on an iPad but doesn't support the iPhone 5 or 6's native resolution. When running scripts, a wallpaper is used for the background (see attached image).
