Biblical software or Bible software is a group of computer applications designed to view and study biblical texts and concepts. Biblical software programs are similar to e-book readers in that they include digitally-formatted books, may be used to display a wide variety of inspirational books and bibles, and can be used on portable computers. However, biblical software is geared more toward word and phrase searches, accessing study bible notes and commentaries, referencing various modern translations, cross-referencing similar passages and topics, biblical dictionaries, original language texts and language tools, maps, charts, and other e-books deemed relevant to understanding texts from a philological approach.
Bible software varies in complexity and depth, depending on the needs of users, just as the purposes of the users vary from devotional reading and personal study to lesson and sermon preparation, inspirational publishing and even further research tools and translations. Basic bible software is typically aimed at mobile phones, and is designed to simply display the text of a single Bible translation, with word and phrase searches as the only available tool. More advanced packages run on personal computers and boast far more features, display a wider variety of theological resources (see above), and may offer features such as synopses and harmonies of the Gospel narratives, morphological and syntactical searches of original texts, sentence diagramming, user notes, manual and dynamic highlighting, lectionary viewers, etc.
Interest in using computers to quickly search the Bible and copy sections of the text quickly into lessons and sermons emerged in the early 1980s.
In 1988, John W. Ellis, M.D. or "Doc Ellis" of Oklahoma City introduced The Bible Library 1.0, the first electronic compilation of multiple Bibles and reference texts. The original CD-ROM contained 9 Bibles and 21 References and was fast and powerful at a time when there were only a couple of slow single Bibles requiring multiple 5¼ floppy disks. 
Bible software was much faster than traditional study tools in a book forms. Early bible software was aimed simply at word and phrase searches in different modern translations. Later, as computers improved in handling foreign language fonts, the original Hebrew Old Testament and Koine Greek New Testament texts of the Bible were added. When working with the original biblical languages, one of the first capabilities was morphology or parsing, providing information on the parts of speech of various words to assist in understanding the intent of the text. At this point many bible software programs emerged which are still in publication today.
Library building 
Most Bible software publishers offer a variety of initial packages from basic, to intermediate, to advanced levels, ranging in price from a free, to well over the price of the computer it runs on. Bible software producers commonly offer customers expandibility—that users can build on their initial monetary investment with the purchase of additional resources such as dictionaries, commentaries, translations, and other inspirational books. Initial packages normally include many bundled works, while add-on titles represent a more significant investment. Normally, the advanced packages include all the features of the more basic packages, though a customer may stand to benefit from two or more bundles by purchasing packages from different publishers—especially those which work seamlessly in the same format.

Mobile platform 
Mobile Bible apps can be best categorized by two primary uses - reading and studying. Most apps will offer little more than the text of the Bible designed to assist users in reading the text of the Bible. Other apps add specialized tools designed to help the student study a passage in the original Greek or Hebrew language. These tools can be as simple as links to Strong's dictionary or as in depth of offering information about parsing and searching on such information. A somewhat comprehensive list of the various Bible Reader and Bible Study apps can be found at KevinPurcell.org.
