St John Reader provides the following functions to help you better read the Bible and other texts:

• Create and edit bookmarks for your favorite passages or to remember your place in the text
• Saves your last-viewed state so that upon returning to the application you will be exactly where you were
• Turn verse-numbering within the chapters on or off (because you may find the numbers to be helpful or a distraction)
• View descriptive information about each book or chapter.
• Read the textual notes within each chapter. Notes are identified by a small "N" that you can click with your stylus in order to view the notes. Additionally, the ability to read notes can be turned on or off. (Currently only the Douay-Rheims translation of the Bible includes viewable notes)

Full version: St John Reader provides the following texts:

• The Holy Bible - Douay-Rheims Version This edition of the Bible was translated from the Latin Vulgate, compared with the original texts, and later revised by Msgr. Challoner in 1752 A.D.. The Latin Vulgate is based upon the translation of St. Jerome around 400 A.D. and it is the official, authorized text of the Roman Catholic Church.
• The Holy Bible - Authorized Version (King James Version) This edition of the Bible was authorized by King James (hence the origin of the two names). Because this translation of the Bible originally included the deuterocanonical books (also known as the Apocrypha), these texts are also included here.
• The Imitation of Christ - by Thomas of Kempis So many Christians have found much wisdom in The Imitation of Christ that it is the most-printed Christian book after the Bible. And it is no wonder, as its pages are soaked in Scripture.
• The Confessions - by Saint Augustine of Hippo Many have been inspired by this autobiography of St. Augustine (354-430 A.D.). He describes the journey of his life and conversion to Christianity.
• The Apologies of Justin the Martyr St. Justin the Martyr (100-165 A.D.) provided two defenses (or apologies) of the Christian faith before his martyrdom.
• Letters of St. Ignatius of Antioch St. Ignatius (~50-100 A.D.), the second Bishop of Antioch, wrote seven letters during his journey to Rome where he suffered martyrdom. Six of these letters were to churches and one is to another Bishop. The letters are as inspiring now as they must have been to the original readers. St. Ignatius of Antioch learned of Jesus Christ from St. John the Evangelist, and his letters provide the earliest recorded reference to the Church as "Catholic".
• The Didache Written perhaps about 150 A.D., this text basically served as a short manual for Christian life and worship. On the Mysteries - by St. Ambrose of Milan
• St. Ambrose (340-397 A.D.) played an influential role in the conversion of St. Augustine. In this treatise he explains the importance of a few of the Sacraments (Mysteries) to the newly baptized
