SheetCue

SheetCue is a mobile rehearsal companion for musicians who already have a score PDF they own or are authorized to use. Import the PDF, review and correct detected measures, set timing, repeats, skips, and set order, then follow the current and next measure or full-page view while playing. It is timing-based: it does not listen to a performance, scan paper, transcribe music, or provide a score catalog. Available on Android and iOS. Free to install; contains ads and in-app purchases.
