Horucco review
A mobile harmony tool for recognizing chords, exploring progressions, and exporting MIDI or WAV.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Horucco is a songwriting and music-theory app for musicians, songwriters, producers, and learners who want to analyze harmony and develop chord progressions on iPhone or iPad. It listens to songs through the microphone to recognize chords, then offers suggestions for musically plausible next chords. Its focus is harmonic exploration rather than generating a complete song: the documented feature set centers on chords, voicings, and progression arrangements.
The workflow connects analysis with editing and playback. Users can arrange chords in a timeline, transpose progressions, adjust chord qualities, extensions, and voicings, and view chord shapes on piano and guitar. The app also explains chord function and other harmonic concepts, making it relevant to learners as well as songwriters working through ideas. Instrument and pattern choices support sketching demos, while MIDI and WAV export provide ways to move a progression into other music workflows. Horucco is a mobile app, not a desktop plugin; its platform fit is strongest for people who want to inspect and shape harmony on an iPhone or iPad.
Horucco has a free plan and two paid options: Horucco Subscription Monthly and Horucco Subscription Annual. The published App Store details list those subscriptions, but regional prices may vary. Choose Horucco if chord recognition, harmonic suggestions, visual chord references, and exportable progressions address the work at hand. It is a narrower fit for anyone seeking melody or bass follow-up generation, or a desktop-first tool. Email is the listed support channel, so buyers who need a broader support setup should weigh that against the app's focused feature set.
