De Het is an Android application developed by Lubos Mikusiak that is designed to help learners of Dutch master the articles of Dutch nouns. It is an educational app that falls under the Education & Reference category. The app contains a dictionary with over 73,000 nouns, and users can search for the articles of a noun by typing the first few characters of the word. Additionally, users can add problematic nouns to their Favorites for later reference.

The app also teaches users several rules and guidelines for determining the articles of nouns. Although the articles may seem random, they are not entirely so. The app provides a fun and interactive way to learn by allowing users to select/guess the articles of nouns presented in random order through the game feature.
