TuneTheory vs Spinz

The tuner and metronome built for musicians who care about precision and feel. TuneTheory hears your instrument ten milliseconds at a time and shows pitch to a fraction of a cent, with a live waveform that stands perfectly still the moment you land the note. Its metronome is sample-accurate: every click lands exactly where it should, at any tempo, no drift, no jitter.
