I like the Holy Trinity Orthodox calendar app. It has the Epistle and Gospel readings (RSV I think) for the day according to the Eastern Orthodox calendar (new or old style), along with a summary of the saints that are commemorated on that particular day.
I use this: https://play.google.com/store/apps/details?id=com.holytrinityorthodox.orthodoxcalendar
Free, and old calendar. Very heavy on the Russian saints though!

This is the one I use! God bless.
