Salat Adhan 2021 is a free Islamic application developed by MezApps for Android users. The app provides accurate Prayer Times for most cities in the Islamic world, including Morocco, using the phone's location (latitude and longitude) based on different conventions. It also has static prayer times for cities that have a fixed time table for prayers. The app offers multiple features, including the ability to set alerts before each Salat Adan, select and download the Adan of your preferred moaadin, and deactivate the sound of Adan Salat with a long click on the volume button.

The app includes a Qibla compass to help users find the direction of the Qibla and also displays the prayer times (Adan) on the notification bar. Additionally, it offers a monthly calendar with the corresponding Hijri date, and users can adjust the prayer times manually. The app also provides more than 130 Quran reciters with the option to download the Quran in mp3 format for offline listening. Furthermore, Salat Adhan 2021 includes various Duaa and Adkar (invocations) that Muslims may need in their daily lives, and it displays Azkar automatically (wake-up, morning, evening, and sleep Azkars).
