I'm using a google Nexus 10 with MobileSheets. I've love to be able to accurately write in some fingering on some of the pages using the annotations section, but even though I have quite small fingers, I still find I can't get the precision needed to hand write small numbers. Can anyone recommend a stylus pen for the Nexus 10? Thanks

The Nexus 10 doesn't support a "true" stylus; you can use a rubber-tip stylus like this:

(There are zillions of these on Amazon, I just grabbed the first search result I found, so don't take the above as an endorsement/recommendation)

However, I should ask why you are hand-writing small numbers. Why not use the text annotation feature? You can make the text box background transparent so the box won't cover up your music.
