The Alfaiz-developed app, "الإختيار لأهم صحاح الأذكار," is a comprehensive collection of authentic Adhkar. The app is based on the book of Sheikh Yahya bin Ali Al Hajoori, may Allah preserve him, and provides an easy-to-use interface for users to access the Adhkar. The app is free to download and is available on the Android platform.

One of the key features of the app is its search functionality, which allows users to search for Adhkar by text or by title. The app also allows users to share and copy the Adhkar, change the font size and background color, and send the app to others. Additionally, the app is ad-free, making it easy for users to focus on their spiritual practice without any distractions.
