PracticeLog - プラログ

Carry your sheet music anywhere and handle annotations, recording, and practice-time tracking in one place. Make daily music practice more fun and more efficient.

PracticeLog is a practice journal app that makes daily music practice more enjoyable and more efficient.

Read sheet music, record your playing, track practice time, and use built-in tools like a metronome and a music dictionary in one app.

What you can do

Smart PDF sheet music management

Import your own PDF scores and view them anytime, anywhere. Organize them with folders and tags, and jump back in from the last page you opened.

Organize by piece

Group score PDFs by piece, link multiple PDFs to the same song, and set titles and theme colors for easier browsing.

Automatically track practice time

While your score is open, the app automatically measures your practice time. Review your progress in graphs and stay motivated by seeing your effort build over time.

Record practice even without opening a PDF

You can also log practice done with paper scores, memorization work, or other activities by piece.

Music dictionary

Look up more than 500 music terms in Japanese, English, Italian, German, and French, with categories and explanations.

Write on scores and move annotations

Write directly on your music with pen, text, and cover tools. Move annotations later and hide parts of the score for memorization practice.

Save page notes

Leave notes on each page of your score and use checkboxes as a to-do list for your next session.

Easy-to-use zoom controls

Zoom in and out directly from the top palette, with controls that stay easy to reach during practice.

Built-in metronome

Set any tempo from 30 to 300 BPM and use multiple time signatures, with accent beats to help keep time.

Easy, high-quality recording

Start recording with a single tap. Recordings are automatically organized by score so they are easy to review later.

Two recording modes are available:

• Standard recording: start and stop whenever you want
• Auto-split save: detects silence and splits files automatically

IMSLP score search

Search for free classical sheet music directly in the app through IMSLP, including composer and title search.

Easier practice review

Create a shareable report from your latest practice record when you want to review or share your progress.
