Euskal Hiztegia is an Android application developed by Borja Dominguez, aimed at helping teachers, students, and anyone interested in learning Euskera, the Basque language. This free application is open to suggestions and improvements, with a feedback section within the app. It offers a range of features, including a dictionary with translations between Euskera, Castellano, French, and English, a translator for phrases between Castellano and Euskera, synonym search in Euskera, and an encyclopedia with articles in Euskera sourced from Wikipedia.

One of the standout features of Euskal Hiztegia is its compatibility with any type of screen resolution and orientation. The app also allows for voice input, and offers well-formatted results for easy reading. It caches search results, meaning that previously searched terms can be accessed offline, and includes a search history and autocomplete function. Additionally, the app offers suggestions for partially written words, making it an accessible and user-friendly tool for learning Euskera.
