Urdu Thesaurus is a free Android app developed by KITAB, designed to help users find synonyms of over 40,000 unique Urdu words and phrases. It offers an easy-to-use and comprehensive language reference resource that can be accessed on both smartphones and the web. The app features 12-point Naskh font, which can be changed by choosing SETTINGS from the menu.

The app offers two types of synonyms - Synonyms and Related Synonyms. The former lists the synonyms of the searched word, while the latter lists the synonyms of the word that occurs elsewhere in the app as a synonym of another word. The app also offers the facility to share synonyms through various media and copy entries for future reference.

However, the app currently only features synonyms and its future versions will include integrated Urdu-to-Urdu lexicons, bilingual dictionaries, and dictionaries of antonyms, idioms and proverbs. Overall, Urdu Thesaurus is a valuable resource for anyone looking to enhance their Urdu language skills.
