The application provides a graphical macOS interface for opening and exploring pprof profiling files, eliminating the need to use the command line. Users can drag and drop pprof files, compare profiles with the `-diff_base` option, and rearrange or remove files quickly. The UI supports both dark and light modes, and sessions can be saved for later review.

It targets developers and performance engineers who work with Go’s pprof tool and prefer a native macOS experience. The app runs the pprof binary as a subprocess, requiring Graphviz for visualizations and macOS Sonoma 14.0 or newer on an M‑series chip; translucent backgrounds are available on macOS Sequoia 15.0 or later.

Implemented with SwiftUI, AppKit, and the Composable Architecture, the software integrates the existing pprof command‑line functionality into a desktop environment while preserving the original profiling capabilities.
