PulseKey is a fast song key detector and tuner built for musicians, producers, DJs, and anyone who needs a clear answer while music is playing.
Tap Listen and PulseKey analyzes audio through your iPhone microphone. Use Key mode to detect the harmonic center of a song, loop, sample, or live performance. Switch to Note mode when you need a precise tuner with note, frequency, and cents readouts.
PulseKey is made for quick decisions in real musical situations: finding the key before mixing, checking a sample before producing, tuning guitar or ukulele, dialing in bass, checking violin or mandolin pitch, or identifying notes while practicing.
