GreekKit is an iPhone application designed to assist users in studying the Greek New Testament. Developed by Casey Perkins, this free app falls under the Education & Reference category. With GreekKit, users can search and identify any word form found in the text of the Nestle-Aland 28th edition of the Greek New Testament.

One of the main features of GreekKit is its ability to create vocabulary lists from all the words in the NA28. These lists can be narrowed down using a diverse range of criteria, allowing users to focus on specific areas of study. The app also offers a powerful flashcard and slideshow feature, eliminating the need to carry physical notecards everywhere.

GreekKit provides a comprehensive search function, enabling users to find every location of a given word in the New Testament. Additionally, it allows users to find all locations where two or more words appear in the same verse, facilitating advanced word studies.

The app also offers customization options, allowing users to change the definition for a word based on their studies. Users can also add notes to words, keeping important information handy. Furthermore, GreekKit provides iCloud sync functionality, ensuring that custom lists, definitions, and notes are available on all devices where the app is installed.

GreekKit now offers in-app purchases, including the text of the Nestle-Aland 28th edition with lexical and search tools, parsings for every word in the NA28, word forms and parsing tools, and Gospel Parallels functionality. This additional content further enhances the study capabilities of GreekKit, making it a valuable tool for those studying the Greek New Testament.
