Accordance is a Bible study program for Apple Macintosh and iPhone, and now Windows and Android, developed by OakTree Software, Inc.[1] Although originally written exclusively for the Mac OS (and then iOS), Accordance was then released in a Windows-native version, although it was available prior to this by using the Basilisk II emulator.
Roy Brown, OakTree Software's president and application developer, created one of the first Bible programs available for the Macintosh, known as ThePerfectWord, in 1988.
[2] The translators of the Holman Christian Standard Bible, completed in 2004, used it for word studies, comparisons and instant searches.
[5] Version 12 (2016) saw a refreshing of the packages available, where, apart from individual modules, users must purchase collections from a specialized stream (Hebrew, Greek, English or Graphics).
There are optional modules, detailed study tools for the original Hebrew and Greek, commentaries and reference dictionaries, with a cross-reference system to interconnect the Biblical text with libraries of ancient extra-biblical material.
