ScoreLibrary

The first score reader with a Time Machine. Scrub annotations from this morning, last night, or last week. Built for daily practice, not the stage.

ScoreLibrary is a music score reader built for daily practice rather than the concert stage. It's the first score app with a real time-machine view of your annotations.

【Time Machine】

Every pen stroke is auto-snapshotted hourly. The vertical slider in the PDF viewer lets you scrub the timeline:

• See only what you wrote this morning
• See only the conductor's notes from last week's rehearsal
• "Pin this as current" promotes a past state without losing the future snapshots

This is unique among score reading apps.

【Smart Japanese Instrument Detection】

When you import PDFs, on-device OCR picks out the instrument and part number, automatically renaming "15_Trumpet3.pdf" to "Murdoch's Last Letter_Tp_3rd.pdf" or your localized equivalent.

• 90+ instrument patterns (Western and Japanese)
• Composer / arranger detection
• Both vertical and horizontal text

【Multiple Import Paths】

• Multi-PDF picker with batched import
• Whole-folder import
• Camera scan to high-quality PDF
• "Open in ScoreLibrary" from Google Drive, OneDrive, Dropbox
• Files app, Mail, LINE share sheet support

【Annotations & Memos】

• Apple Pencil pen input
• Inset memos (drop a dot anywhere on the page) with text, handwriting, and photo attachments
• Fast page-turn mode and continuous scroll mode

【Concert / Event Management】

• Per-event annotations (your notes for Concert A don't bleed into Concert B even on the same score)
• Setlists with reordering
• Auto-generated mute lists for what to bring

【Practice Tools】

• Chord card with audible chord lookup
• Score reading card for note name / interval reference
• Built-in metronome

【Trilingual】

Japanese / English / 简体中文 with instant in-app switching.

【Pro Tier (one-time $4.99)】

Unlocks Time Machine slider operation, "Pin this as current," paw- shaped slider thumbs, an alternate paw-stamped app icon, and a faint paw-print decoration across the tab backgrounds.

Snapshots are recorded in the background for everyone, so Pro can be purchased anytime later without losing your past practice history.

One-time purchase. No subscription.
