moduLab Pro

Practice with your own music: transpose pitch, analyze chords and rhythm, create a timed on-device transcript, and use the tuner and metronome.

moduLab Pro is a music workspace for practicing with your own audio files on iPhone and iPad.

PLAY AND ORGANIZE • Add audio files from Files. • Sort, rename and manage your tracks. • Listen with Lock Screen controls, CarPlay, AirPlay and external-display support.

TRANSPOSE • Shift pitch in real time by semitones or cents. • Keep vocals closer to a natural tone with formant correction. • Follow the current and upcoming chords while the track plays.

LYRICS AND ANALYSIS • Create a timed Raw transcript from your audio entirely on device. • Optionally use Context Refined, which makes conservative word changes using only repeated evidence within the same recording. • Switch back to the unchanged Raw transcript at any time. • Analyze chords, rhythm, BPM, meter and tonal structure on your device. • Adjust chord density and explore capo suggestions and guitar chord shapes.

PRACTICE TOOLS • Measure instrument pitch with the tuner. • Practice freely with the metronome or follow the detected song pulse. • Show lyrics and chords on an external display in a teleprompter-style view.

PRIVACY Imported audio files are not uploaded to a server operated by the developer. Raw transcription, Context Refined processing, and core chord, rhythm, tempo and tonal analysis run on the device. No external lyrics catalog is queried. Limited third-party network requests may be made for music identification, artwork lookup, advertising, subscriptions, model downloads and version checks. See the Privacy Policy for details.

FREE AND AD-FREE OPTIONS The free experience may include an adaptive banner and interstitial ads. The yearly auto-renewable subscription removes banner and interstitial ads while its entitlement is active. The App Store shows the applicable price and currency before purchase. The subscription can be managed or canceled in App Store account settings.

Music analysis, the Raw transcript and Context Refined suggestions are automatic estimates and are not guaranteed to be complete or accurate. Any displayed model confidence is not a verified accuracy rate. Import only audio you are authorized to use, copy and process.
