Vietnamese Dictionary: EVDict is a free iPhone app developed by VM Mobile Team. It serves as a comprehensive Vietnamese - English and English - Vietnamese dictionary with over 150,000 word entries. The standout feature of this app is that it stores the dictionary data offline, eliminating the need for an internet connection to look up words.

One of the key features of Vietnamese Dictionary: EVDict is its ability to search for Vietnamese words without accent marks. For example, if you type "thuc an," the dictionary is able to look up "thức ăn" (food). Additionally, the app supports text translation between English and Vietnamese, making it a useful tool for bilingual users.

Another impressive feature of this app is its audio pronunciations in both Vietnamese and English, including UK and US pronunciation. Users can also take advantage of the app's ability to read aloud full paragraphs in both languages.

Vietnamese Dictionary: EVDict also offers a flashcard feature with an intelligent scheduling algorithm, allowing users to learn words effectively. The app comes with several wordlists of the most common Vietnamese words, as well as English wordlists for exams such as TOEFL, IELTS, GRE, and more.

Furthermore, the app provides a quick image search for any word, enhancing the user experience. Users can also create custom wordlists, adding a personalized touch to their language learning journey.
