The TOEIC Training Tool is a simple yet highly effective app designed to help users improve their English grammar and vocabulary. This app focuses on questions in a format similar to that of part 5 of the TOEIC exam. The questions are divided into grammar and vocabulary categories, allowing users to target specific areas for improvement.

To use the app, users can select any item from the main list and choose a sub-category. They can then answer the displayed questions by selecting options a, b, c, or d. After answering all the questions, users can click on the "Get score" button to see their results. Right and wrong answers are indicated with appropriate icons. For revision purposes, users can add questions to the "My Revision List" category by selecting the checkbox. Additionally, there is a practice test feature that randomly selects 30 questions from all categories to assess overall progress.

The TOEIC Training Tool offers additional functionality through a long press on any text in the questions and answers. Users can define the selected word to get its English definition, pronounce the word, or translate it to a chosen language in the settings. It's important to note that an internet connection is required for the define and translate features.

The app includes a settings page accessible from the Android options menu. Users can customize the maximum number of questions for each category and the random practice test. They can also select the target language for word translations.

This app is suitable for anyone preparing for the TOEIC exam or any non-native English speaker looking to enhance their grammar and vocabulary skills.

Future updates will bring more questions, categories, and functionality to the app. Users can provide feedback and suggestions to the developer for further improvements.
