I highly recommend the iPray BCP app for those who have an iPhone or Android smartphone. It has Morning and Evening Prayer from the 1662 CofE BCP, and Midday Prayers and Compline from the 1962 Canadian BCP. My only problem with it is that it doesn't have a full saints day calendar, but I add a Hail Mary after the Our Father in Mattins and Evensong. Otherwise it is great and automatically has the lessons and psalms appointed, the lessons are from the KJV and 1922 Prayer Book lectionary, and the psalms are from the Coverdale Translation. http://ipraybcp.com/
If I had an iPhone or such thing, I'd definitely have used it. 1662 is always good, no matter its format.
I use Pocket Common Worship and Prayer which has Morning and Evening Prayer from both the 1662 BCP and Common worship. It also has Night Prayer in trad and contemporary versions. Like iPray, the Psalms and Readings are automatically in place. There's another app by the same author called Open Prayer Book which has Offices from many other sources and allows custom liturgies. http://truthforme.co.uk/solus/#android As much as I like technology I prefer books!
I prefer books too. But the question then becomes: is there such thing as a BCP with enough ribbons? I have an edition with 3 (and wish it had 5 or 6)...the newly published batch only has two. I'm trying to preserve mine as long as possible. Ribbons rule. The app does look cool.
Mine came with two blue ribbons, which I assume were to hold the place of the Collect and whatever place one needs to preserve in the daily the Office. I had to tape a third ribbon into the spine to turn to the Psalms each day. The App does sound very helpful, but for me holding a book just feels more "authentic". It's closer to God to hold the binding, the paper, and the ink in my hands - something about a Kindle program or App makes it too distant, ghostly, and ethereal. Surely this is gnosticism being forced on us!
