## Description

Import your lesson-book tracks, run the metronome over them, keep the sheet photo in view, record your takes, and tune up — all in one focused practice app.

Metro Sound is a practice companion for musicians who work from a lesson book.

Import the practice tracks that came with your book, organize them into exercises, and get the tools you actually reach for while practicing — an overlay metronome, a tuner, sheet photos, and a recorder — in one focused place.

TRACK PLAYER
• Import audio from Files, iCloud Drive, or anywhere your device can reach. Files are copied into the app, so deleting the original won't break your library.
• Numbered filenames become ordered, titled exercises automatically.
• Waveform, adjustable playback speed for slowing down hard passages, and progress you can mark as you go.

OVERLAY METRONOME
• A click that runs over the playing track as a separate audio stream, with its own volume and mute — so either the music or the click can lead.
• Tap tempo, a tempo dial, and time signatures with an accented downbeat.
• A swinging pendulum you can watch instead of hear.
• Tempo and time signature are remembered per exercise.
• A full metronome screen for tempo work without a track.

TUNER
• Microphone-based pitch detection, live and entirely on your device.
• Letter or solfège note names.
• Persian quarter-tones (koron and sori) alongside standard chromatic tuning.

SHEET PHOTOS
• Attach photos of the printed exercise to any track and read the notation while the audio plays.

PRACTICE RECORDINGS
• Record your own takes next to the lesson track and keep them with the exercise they belong to.

SHARE A WHOLE BOOK
• Export a book — or your entire library — as a single package and send it to a student, a teacher, or your other device.
• Imports show a preview of what's inside, and merge into an existing book or arrive as a new one.

PRIVATE BY DEFAULT
• No accounts, no sign-in, no analytics, no ads.
• Your library, recordings, and photos live on your device. Nothing leaves it unless you share it.
• The tuner's audio is analyzed on-device and is never saved or transmitted.

LIGHT AND DARK
A studio-dark look by default, a clean light theme when you want it, or follow the system automatically.

METRO SOUND PRO
Metro Sound is free to use, and the metronome and tuner are never restricted. Your first book is free. Metro Sound Pro is a one-time purchase — not a subscription — that unlocks an unlimited library and practice recording.
