PitchLog is an intonation trainer for singers and instrumentalists who want to sing in tune and play in tune — by ear, not by staring at a screen.

Most pitch apps work like a live vocal pitch monitor: you watch the needle while you perform, and your eyes do the work your ears should be doing. PitchLog works the other way round. Pitch feedback stays hidden while you sing or play, and you use it as a pitch checker afterwards, when you review the take.

HOW IT WORKS
1. Start a take and sing or play naturally.
2. Perform without live pitch feedback pulling your attention away from the sound. This is ear training built into every practice session: listen first, judge for yourself, then check.
3. Stop the take. The pitch tracker has recorded every note — now review which notes were sharp, flat, or unstable, and listen back with the pitch trace.

REVIEW EVERY TAKE
• Note-by-note summary showing sharp, flat, and unstable notes
• Full pitch timeline for the whole take
• Accuracy and stability scores
• Audio replay alongside the pitch trace, so you can hear what the chart shows
• A clear view of the moments worth practicing again

Made for voice and for melody instruments — use it as a singing pitch trainer in vocal practice, or to check intonation on violin, flute, trumpet, saxophone, and other single-note instruments.

PRACTICE TOOLS INCLUDED
• Drones (reference tones) and a built-in metronome
• Transposition, adjustable note range, reference pitch, and filtering
• Feedback options, including auto-reveal between phrases and optional live pitch display
• Offline practice after installation

FREE AND PRO
Free includes unlimited practice takes, with audio replay for takes up to 60 seconds. Pitch feedback, drones, the metronome, chart-only takes, and offline practice are all available in Free.

PitchLog Pro extends replay to takes of up to 5 minutes, for one year. Renew manually when you want to continue — there are no automatic renewal charges.

PRIVATE BY DESIGN
No account. No ads. Your microphone audio, detected notes, pitch measurements, and take results stay on your device and are not uploaded by PitchLog.

A NOTE ON ACCURACY
PitchLog is designed for practice feedback and spotting patterns in your singing and playing, not laboratory-grade measurement. Room noise, microphone quality, and tone clarity can affect results.

Practice by ear first. Then review which notes were sharp, flat, or unstable.
