Ultimate Lac Viet Dictionary (Lac Viet)

Ultimate Lac Viet Dictionary is a Vietnamese dictionary app for iPhone and iPad. It’s best for learners who want fast word lookup while reading, studying, or translating short bits of text.

The core is English to Vietnamese and Vietnamese to English lookup with a large entry database, plus cross references so you can tap words inside definitions to keep exploring. You also get bookmarks and a Word of the Day style feature for lightweight daily vocab practice.

You will build vocabulary and reading confidence, and there are extra sections like Grammar and a Translate feature, but it won’t replace speaking practice or guided lessons. You can start with the free version and optionally upgrade via in app purchase on the App Store.
