v2.1 — A practice-focused music score app with a unique time-travel feature. 【Time Machine (new)】 Annotations now have a timeline you can scrub. Tap the clock icon at the top right of the score viewer to open a vertical slider on the right edge. Drag the two thumbs to narrow the time range and see only what you wrote this morning, last night, or last week. "Pin this as current" preserves a past state as the new live version without losing the future snapshots — slide back and the heavier versions are still there. Score annotations are auto-snapshotted hourly, so you never lose what your conductor told you in last week's rehearsal. 【Easier Import】 Open PDFs directly from Google Drive, OneDrive, Dropbox, the Files app, Mail, and any iOS share sheet. ScoreLibrary now appears as a destination when you "Open in" a PDF. 【Stable Multi-File Import】 Bulk PDF import is now reliably faster and won't freeze on memory-tight devices. Hour-by-hour processing. 【Pen Drawing Reliability】 Fixed an issue where pen mode could break across page changes and lose strokes. Apple Pencil now works smoothly across the whole score. 【Polish】 - Score Reading and Chord cards now open at the top-left and top-right of the screen so they don't overlap on launch. - New "Auto-OCR on import" setting in case low-memory devices need it off. 【Pro Tier (one-time $4.99)】 v2.1 introduces an optional Pro upgrade. It unlocks Time Machine controls and "Pin this as current," swaps the app icon to a paw- stamped variant, and sprinkles a faint paw trail across the tab backgrounds. Snapshots are recorded for everyone in the background, so buying Pro later still surfaces your full practice history.
