İKE: İngilizce Kelime Ezberle is an Android application designed to help users learn English words, which is one of the most challenging aspects of learning the language. The app features nine different categories of words, including "Beginner Level Words," "Intermediate Level Words," "Advanced Level Words," "High-Level Words," "Most Used Words," "KPDS, YDS (Foreign Language Exam)," "TOEFL IBT," "GRE," and "Words You Already Know."

With over 9000 unique words available, users can learn and memorize words using five different testing techniques for each category. These techniques include multiple-choice tests in English with Turkish answers, multiple-choice tests in Turkish with English answers, matching tests where words are matched with their Turkish meanings, and two listening comprehension tests.

The app also features an intelligent memorization system. As users answer questions correctly, words will be added to their memorization list once they reach a certain threshold, and those words will no longer be included in the tests for that category. Users can also update their memorization list for each category.

İKE: İngilizce Kelime Ezberle is completely free, and the developers are open to feedback and suggestions for improving the app.
