For a mere 6 euros you get the craziest app, which I only imagined to exist. The recognition of sheet music works reasonably well, it might miss a note or two in an easy part. It struggles more when there’s sixteenth flat or sharp notes. Be sure to take a well lit photo and include all of the bars, including the connecting pieces which display different voices. You also get a ton of instruments, one sounding better than the other but overall good, you can transpose, speed up or change the tuning. Add other pages, save files, export as audio or other sheet music files. I can imagine so many cases in which this app is a great convenience for someone who works with music. This is the definition of bang for your buck.
