Harmoniqs vs PulseKey Tuner

Harmoniqs turns any audio file into a detailed musical analysis in seconds. Upload a song, record live audio, or use the built-in real-time tuner to identify pitch on guitar and bass -- all from one clean, powerful app. AUDIO ANALYSIS Drop in any MP3, WAV, FLAC, OGG, or M4A file up to 200 MB and Harmoniqs instantly detects the musical key with major and minor scale identification, the tempo in BPM, and the dominant notes present in the recording. Perfect for musicians learning songs by ear, producers checking keys before a mix, or anyone curious about what makes a track tick. REAL-TIME CHROMATIC TUNER The built-in tuner listens through your microphone and continuously detects pitch, giving instant feedback with a cents meter showing exactly how far you are from perfect pitch. Switch between guitar and bass tuning modes, tap a string to lock your target note, and see whether you are flat, in tune, or sharp. No clip-on tuner needed. CIRCLE OF FIFTHS Every analysis includes an interactive circle of fifths that highlights your detected key and its relative major or minor -- a fast visual reference for songwriting and improvisation. DIATONIC CHORD SUGGESTIONS Get all seven chords that naturally belong to your detected key, complete with Roman numeral notation and chord quality. Tap any chord to learn its degree and role within the scale. CAPO AND TRANSPOSITION TOOL Transpose the detected key up or down by semitone and instantly see guitar-friendly capo positions that let you play using open chord shapes. Great for adapting songs to your vocal range. RECORD, PLAY BACK, AND SAVE Record live audio through your microphone for instant analysis, then play it back with a tap-to-seek progress bar. Every result is saved automatically and cached locally so your history is available even offline. DARK MODE AND OPTIONAL ACCOUNT Full dark mode support, either following your device setting or toggled in Settings. All core features work with no account required -- sign in optionally to sync history across sessions. SUPPORTED FORMATS MP3, WAV, FLAC, OGG, M4A -- files up to 200 MB. Whether you are a guitarist tuning up, a producer hunting for the key of a sample, a student studying music theory, or a curious listener -- Harmoniqs gives you professional-grade tools in a simple, elegant package.

PulseKey remembers your last mode, so you can pick up where you left off. No account, advertising or developer analytics. Microphone audio and imported files are not uploaded by PulseKey. A NOTE ABOUT MEASUREMENTS Key and pitch readings are estimates and depend on the instrument, room noise and microphone. For tuning, play one clear note at a time. Complex music can have more than one plausible key. Experimental drum readings may follow an overtone rather than the fundamental. Pro is an optional one-time in-app purchase.
