George R.R. Martin’s “A Song of Fire And Ice” saga fans can now learn how to speak Dothraki with the help of an app.

Martin’s publisher, Random House, has created an app that teaches fans how to speak Khal Drogo’s native language. The app is called Dothraki Companion, and is available for the iPhone and iPad for $3.99.

The app was created with the help of David J. Peterson, the person responsible for coming up with the Dothraki language, according to The Guardian. Fans will be able to learn “conversational dialogue” by using more than 300 vocabulary flashcards in the app to help with the learning process.

There is also an online course and book available for those who wish to take their Dothraki knowledge to the next level. The app, online course and book are available on the Living Language website, a source for fans to learn any fictional language.

The Dothraki book “features a pronunciation guide, basic phrases, a detailed guide to grammar, 250 vocabulary words organized in eleven thematic lists, a dialogue, culture notes, and 50 written exercise questions to test your Dothraki," according to Living Language. "The accompanying one-hour audio CD features pronunciation, phrases, key grammar examples, vocabulary, and a dialogue.”

The basic course book and CD costs $19.99 and will include the following:

1. A pronunciation guide.
2. Basic phrases.
3. A detailed guide to grammar.
4. 200 vocabulary words organized in eleven thematic lists.
5. A dialogue.
6. Culture notes.
7. 50 written exercise questions to test your Dothraki.
