This dictionary app was my first attempt to learn how to develop for Windows Phone, back in 2011. It lets you look up words and expressions as you type, using either an English-Hungarian or a German-Hungarian dictionary in the chosen direction. You can build and manage a list of your favorite words, and if you need to, you can translate any freely entered text between a dozen languages via Bing Translator. The dictionary itself doesn't require internet connection, works completely offline.
You can also find it as "Magyar szótár" in the Hungarian app store.
