iPad score apps

ForScore is the only one I’ve tried. It’s great, fairly intuitive to use. I’m not very techy.  Easy to import scores from IMSLP, and PDFs I’ve made using Genius Scan. It can also use  face recognition to turn pages!  A case of be careful what you wish for if you don’t want them to start flipping because you are over emoting or grimacing in a difficult passage :) 

I am happy with ForScore for general use.  If you like Henle publications, as I do, and don't mind paying (most likely for scores you already own in print!), then I can recommend the Henle app too.  

I use mainly Piascore. It's great, that IMSLP is sort of "integrated" in Piascore, so you can directly import IMSLP sheet music to Piascore, which is quite comfortable. Furthermore Piascore has the face recognition-page-turning feature built in.
