Violin Tuner & Intonation
Ear Training & Scale Practice
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Tune your instrument, see your pitch, and practice with a metronome for free. Explore guided scales and arpeggios with Pro.
Tune your violin and improve your intonation with live pitch feedback, fingerboard exploration, ear training, and a built-in metronome.
See and refine your intonation
Live pitch feedback shows whether each note is sharp, flat, or centered. Adjust the A4 reference to match your instrument or ensemble.
Practice scales with a clear target
Guided practice in Pro follows major and minor scales, arpeggios, and combined exercises. Choose your key, octave range, direction, and rounds. Play at your own pace or follow a set tempo with an optional count-in.
Hear notes and explore the fingerboard
Connect written notes with fingerboard positions, explore double stops, and train your ear by finding the notes you hear. Preview notes with sampled bowed or pizzicato violin sounds, or a synthesized reference tone.
Review and repeat
Capture pitch samples, review intonation note by note, and repeat an exercise with the same setup. Takes store pitch data only; microphone audio is not saved.
Keep a steady pulse
Use the built-in metronome with accents, subdivisions, Tap Tempo, Tempo Trainer, and Quiet Count.
Start free, go further with Pro
Start with live pitch feedback, first-position fingerboard exploration, basic ear training, and the metronome. Pro adds guided practice, full fingerboard access, key highlighting, complete take history, and advanced intonation controls. Choose a monthly or yearly subscription, or a lifetime purchase. Subscriptions renew automatically unless canceled in App Store settings.
