Detect song keys, tune instruments, and read notes from your iPhone microphone. One press gives you clear, on-device music analysis.
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.
Features:
• One-tap song key detection
• Microphone-based listening
• Audio file loading
• Key Harmony mode for songs, loops, and samples
• Single Note mode for pitch detection
• Cents and Hz readouts for tuning
• Chromatic, guitar, bass, ukulele, violin, and mandolin presets
• Open Key support for DJ-friendly harmonic mixing
• Clean visual analyzer for note strength and confidence
• On-device audio analysis
• No account required
PulseKey keeps the workflow simple: listen, analyze, decide. No menus before the answer. No clutter. Just the key, pitch, and tuning information you need.
