....and not so great ones.
After having some issues with our iPad, I discovered another reading app called Epic!. Epic! has a variety of books for kids sorted by age/grade level and themes. It is available on a number of devices: computer, iPad and android. Once downloaded, a teacher account can be made for free. Educator account is free while all others are paid. One helpful feature is that it stores a log of books read and assigns badges as a reward system. Some books are as read only while others are read to the user. It seems like the books that are dubbed with sound are less common though easy to find.
One major drawback; it's glitchy. In order to read a book during story time I have to download it first as it often does not play live. If I try to play a book live, it hangs up, stops or has to reload and reloads from the beginning of the app login. Today we tried to read a book from the site live and one page was reading while the following was silent. So we improvised and had one page read to us while we read the following pages.
All in all, it's a good potential site, but I won't use it in my story time again.
But for the price of FREE it's definitely worth a try: https://www.getepic.com/
