This chromatic tuner uses an optimized McLeod Pitch Method (MPM) for fast, accurate frequency analysis and low-latency note detection. When the signal is loud and clear, background noise is ignored completely. When the signal is quiet, the app automatically raises sensitivity so you can still get a solid reading. A precise metronome is included, with fully adjustable BPM and beats per measure. It can optionally run in the background, so the beat continues while you switch to other apps
