OnYourWay (ובלכתך בדרך) is a great iPad app that gives you a decent collection of sefarim for free (link). The books are well organized and the Chumash section allows you to choose each chapter and the commentaries you want (Rashi, Ramban, Ibn Ezra and more). Includes all of Tanakh, Mishnah, Gemara, Shulchan Arukh, some mussar and machashavah books and more.
Extremely easy to use and best of all… it’s free. Thanks to Roi Reshef who created this app.
