I purchased a couple of those in Google Play Store, which works well for me, but I don't jam with them. Reading the books in the Chrome browser works very well, only I don't believe it will stop your screen from shutting down to save power, so you may want to adjust those settings on your PC to make sure your screen doesn't blank mid-song.

I see you can purchase a (cloud-based, requires internet connection) e-book direct from the publisher, Hal Leonard at

And another option would be to get the individual songs from SheetMusicDirect.com at
https://www.sheetmusicdirect.com/Search.aspx?query=The Daily Ukulele ...expensive if you wanted all of them, but they also have a subscription model which would give you all-you-can-eat access to everything on SheetMusicDirect.com (again via cloud access using their web-based app etc,) for a monthly fee. I use SheetMusicDirect.com a lot myself, but usually to purchase individual song PDFs which I can load into MobileSheets (an app available on PC, Apple or Android devices) or print off; it's handy to have everything I've purchased in their app too. I haven't tried their subscription service.
