I try to pray some of the Book of Common Prayer daily. Usually morning prayer on the bus to work, evening prayer on the bus ride home and compline before bed. I've been semi consistent about it.
Are you using the Anglican BCP or is there a Presbyterian text of the same title that I'm unfamiliar with?
I use the Book of Common Prayer.
There is a Presbyterian 'Book of Common Worship' which is basically the BCP with the more Catholic bits removed, and the format of the sacraments changed to fit our tradition,but I haven't been able to find a mobile friendly version of it.
