Electronic Rosary Good Example

The application is aimed at devout Muslims looking for an app to help them conduct their daily religious practices. It offers various services, including an electronic rosary and Qur'an. The electronic rosary enables users to record the number of praises throughout the month and provides Azkar, a set of recitations of verses. When installed, the electronic Qur'an allows users to save their progress and continue reading from where they left off.
