SheetViewer vs shortReverse

SheetViewer — More than reading scores. Practice with your digital piano. 【Connect once, follow-play everywhere】 Pair Bluetooth or wired MIDI (keyboard / digital piano) once—it works app-wide. Open any MusicXML score and start follow-play instantly, without reconnecting for every piece. The score scrolls with playback; every note you play is judged in real time with wrong-note highlighting. When you finish, review your accuracy—like having a coach beside you. 【Crisp vector MusicXML scores】 Sharper and infinitely zoomable compared to PDF or images. Import .musicxml, .mxl, .mscz, .mscx, or .xml (e.g. exported from MuseScore). Sync your library across iPhone and iPad with iCloud. 【Start practicing right away】 Import your own licensed scores and use the same follow-play and stats workflow. 【More practice tools】 • Playback with auto-scroll to preview how a piece sounds; adjust tempo • Color markings on the score surface • Metronome and volume controls • Sight-reading mini-games (e.g. chord bubbles; MIDI required) 【Pro subscription】 After purchase, you can practice up to 3 different scores per day (follow-play, playback, etc.). SheetViewer Pro (monthly or yearly) unlocks the full built-in demo library, unlimited practice, full stats & markings, and unlimited mini-games. 【Who it’s for】 • Pianists with Bluetooth MIDI keyboards or digital pianos • Musicians, ensembles, and students who work with MusicXML • Anyone who wants follow-along practice and accuracy feedback on iPad / iPhone 【Support】 Questions or a score that doesn’t render correctly?
