Could you build this?
Partial A metronome and chord library are simple to build, but building an accurate, low-latency pitch detection algorithm (tuner) across iOS and watchOS requires specialized DSP expertise.
What it would actually take: The audio pipeline requires real-time digital signal processing (DSP) using YIN or MPM (McLeod Pitch Method) algorithms implemented in Swift/C++ to isolate fundamental frequencies and filter out harmonics in noisy environments. The watchOS companion and widget integrations demand precise power management and low-latency audio capture via AVFoundation.
