ScoreLibrary

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】

- Apple Pencil pen input
- Two page-turn modes: paper Page Curl and smooth Slide
- Attach photos anywhere on the page

【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
- Add multiple flyer images per event (front, back, handouts),
viewable full screen
- 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 with compound-meter support (6/8, 9/8, 12/8)

【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.
