Golden-Soft's القاموس المحيط is a free Android application that provides users with a comprehensive Arabic dictionary. The dictionary is based on the work of the famous linguist Majd al-Din al-Firuzabadi, who wrote the original text in the 9th century. The dictionary is organized alphabetically, with each entry containing a definition, synonyms, and related words.
