Best for

iOS and macOS developers who can record a trace but struggle to read Instruments.

Why it deserves attention

RocketTrace analyzes Time Profiler, hangs, animation hitches, Swift Concurrency, and SwiftUI data, then ranks findings by measured duration, frequency, and execution context instead of leaving you with a wall of graphs. Each finding can be copied as an investigation prompt for a coding agent, and a second comparable trace shows before-and-after deltas. Analysis runs locally with your Xcode installation, so traces and source paths stay on the Mac. The app is a free download with the first three analyses included, and requires macOS 26 and Xcode 27 or newer. It is new, paid beyond the free analyses, and only covers Apple platforms.
