Dua Azkar is an iPhone app developed by Ahsanul Haque that aims to provide users with a collection of authentic Duas from the Quran and well-established books like Hisnul Muslim. The app focuses on Duas that are often memorized but not implemented by the majority of Muslims.

The main features of Dua Azkar include authenticity, simplicity, and practicality. All the Duas in the app are sourced from reliable Islamic texts, ensuring their authenticity. The chapters in the app have been carefully compiled, and only essential features and functions have been added to ensure ease of use for users of all age groups.

The app is designed to prioritize the most powerful Duas and Adhkar that, if implemented, can bring success to an individual's life. Whether you are a new Muslim or a young child, Dua Azkar is accessible and beneficial for all stages of life.

If you come across any errors or mistakes in the app, you can contact the developer through email at their website duaandazkar.com, or via Facebook. The developer is committed to correcting any mistakes in future releases.
