OmniObjectMeter

OmniObjectMeter is a tool that makes it easy for Cocoa and Unix developers to find and fix memory leaks, excessive allocation operations, "zombies", prematurely deallocated objects, and other performance issues. The end product is faster and more robust applications.

Rather than searching through the thousands of objects and allocation events in a program, you can use OmniObjectMeter to quickly seek and destroy problematic code, and spend your time fixing problems rather than looking for them.
