The project implements a native SwiftUI tuner that captures microphone audio, runs FFT and autocorrelation to determine pitch, and shows note, cents and frequency on a dynamic gauge. It targets musicians needing a portable, precise tuner without external hardware. The code includes a full app structure, audio analysis utilities, and UI components, making it ready to build and run. Compared to generic tuners, it offers sub‑cent accuracy and a polished animated interface.
