Smart Dictionary is an Android application designed to help users learn English words. The app allows you to add new words to your dictionary, and then tests you on their translations. The more you correctly translate a word, the less frequently it will appear in the testing, and vice versa. Moreover, if you provide the wrong answer, the app will prompt you to try again soon.

One of the best features of Smart Dictionary is that it allows you to download a dictionary from your device or a text file from your computer. Additionally, the app comes with a built-in database of English words. This makes learning English with Smart Dictionary a breeze.
