CueFlip: Sheet Music Reader

This update redesigns CueFlip for iPhone Duo and brings Wink to Turn Pages, a docked piano, camera scanning, stamps, and practice statistics. -- Device Support -- - Designed for iPhone Duo: redesigned for the inner and outer displays and half-open use, with two pages on the inner display by default and the controls clear of the hinge. -- New -- - Wink to Turn Pages: close your right eye to turn the page and your left eye to go back. - Docked Piano: the piano opens under the score, so you can read and play at the same time, in three sizes and with adjustable concert pitch. - New Piano Sounds: Analog Pad, Synth Pluck, Synth Lead, and Synth Bass. - Piano in Other Apps: use the CueFlip piano as an Audio Unit instrument in GarageBand, Logic Pro, AUM, and more. - Scan with Camera: photograph a paper score and CueFlip flattens curled or tilted pages, turns them upright, and splits an open book into two pages. - Stamps: 179 music symbols, including dynamics, articulations, fingerings, bowings, notes, rests, clefs, and guitar marks. Tap to place, hold to move, drag to the bin to delete. - Practice Statistics: practice time, streaks, a practice calendar, your busiest practice times, and page-turn accuracy over 7 days, 30 days, or 12 months. - Score Links: link repeats, D.C., and Coda, then tap to jump there and back while reading or performing. - Crop Margins: detect and trim blank margins so the score shows larger and clearer, without changing the PDF. - Custom Covers: use any page, or an image from Photos or Files, as a score's cover. - Import Images: create a score from photos or image files, one page per image. -- Improvements -- - Score following: finds your place again after losing it, catches up a missed page turn, corrects mistaken jumps backward, and turns again a page you went back to by hand. One slip no longer costs the rest of the performance. - Eye Comfort: retuned to the IEC 62471 and CIE S 026 standards. In optical benchmarks, the default setting has about 31% less blue-light hazard and 28% less melatonin-suppressing light than a white page. - Page-turn statistics: every valid performance now counts, with a new accuracy calculation, wrong and missed turns, and a redesigned view. - Annotations: draw a line, circle, triangle, or rectangle and hold for half a second to turn it into a clean shape. - Metronome: tempo range expanded from 30–400 BPM to 1–500 BPM. - Two-page view: now on iPhone in landscape, with the first page on the left or the right. - CueFlip reopens the score you were reading, on the same page and at the same zoom. - Manage Pages: select several pages to duplicate, move, or delete at once, with sharper thumbnails that show the pages on screen first, even in huge scans. - The large widget shows two pages of a portrait score side by side. - The tutorial is now an interactive eight-page guide in all 13 languages. - Fixed sharing scores that haven't been taught yet, swipe-back in folders, and more, with major improvements to performance, memory use, and stability.
