Profilers, while they are technically still debuggers, are designed to debug a different element and from a completely different perspective. A profiler is a much lower-level debugging system that is looking at performance and what is attributed to the performance as it stands during execution.

Like standard debuggers, these tools can easily give you insights that lead to finding solutions to high-level problems, but will generally help you determine why your application is running at 14 FPS instead of 60.
