More Lectionary: Of course, there's an APP for that.

Crushed Red Pepper: Their website. At iTunes. The price for the basic service is $.99. To get the "Daily Office" (daily Bible readings), you need to buy the $1.99 add-on. It's the Daily Office I was looking for. Because the scriptures are right there, the total cost seems very reasonable. The lectionary source is slightly different from the one on the PC(USA) website. I haven't quite sorted out the differences, but the app choices appear to me to be very satisfactory. (One has two lectionary source versions to choose from in the Crushed Red Pepper app.)
