زاد المؤمن is an Android app developed by almahdyoon, available for free in the Education & Reference category. The app is designed to help Muslims with their daily prayers by calculating accurate prayer times based on their location. Users can also manually search for prayer times or their location on the map. The app provides a call to prayer for Fajr, Dhuhr, and Maghrib prayers.

One of the app's unique features is its Qibla direction finder, which helps users determine the direction of the Kaaba from anywhere in the world. Additionally, the app provides an easy-to-use Quran reader with search functionality. The app also includes some prayers and devotions from the books of Imam Ahmad al-Hassan (peace be upon him).
