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.
