Hi,
 
I'm investigating moving my piano sheet music to a tablet.  I believe I'm going with an android device (Samsung). I'm researching which software to use to store my sheet music and Mobilesheets seems to be highly rated.  Would someone be able to answer the following questions I have about the software:

Can I take a picture of a sheet of music and have it imported into mobilesheets?

Can I scan sheet music and save it into a pdf file and then import that file into mobilesheets?

Is there an option that will automatically highlight sharps and flats?

Can I remove a note or add a note?

Is the above available on the free version?  

If I purchase the software, is it a one-time purchase?

Thanks, Tom
