Zar Dictionary is an educational reference tool available for iPhone users. Developed by Jiasaz Company Ltd, this free dictionary app is based on the Longman dictionary and offers a collection of around 15,000 English words, with continuous updates. Each entry not only provides meanings but also includes IPA symbols for pronunciation, stress placement identification, and word categorization.

Moreover, Zar Dictionary goes beyond individual words by including phrases that can alter meanings. The app also features useful appendices like common abbreviations, countries and currencies lists, irregular verbs, and irregular plurals. Users can benefit from both UK and US pronunciations, making it a comprehensive resource for language learners.
