It depends very much on what you call "score".
The only music data that MobileSheets can transpose is text (ChordPro) format. That means lyrics + chords.
Writing lyrics + chords can be done with any convenient text editor. My personal favourite is GNU Emacs with Chord mode.

Thanks. Actually i wanted to write simple musicsheets on my tablet manually, one system (i dont' know how to say it in english) or two systems max. for piano.
Is there any application that you are using for writing notes?
