The Story behind this application started when I was memorizing the most essential 570 IELTS words, based on popular learn resources for IELTS. The 570 words are useful in each section of IELTS. However, the process to memorize these words was hard and boring. I tried ways such as flashcards and reminders. Moreover, I researched for an application that offers a new style to memorize the 570 words, and I did not find what I am looking for. Thus, I decided to create this application to help IELTS students. The app presents an enjoyable way to improve IELTS vocabulary with the important 570 words.
