Kaffaratul Majlis Reminder is a free Android app developed by Walid Khedr - WIK4Apps. This app reminds the user to recite the "Kaffaratul Majlis Thekr" prayer after each phone call. This prayer is usually recited at the end of a gathering, including phone calls. The app also includes an Azkar Reminder that reminds the user to praise Allah through auto-azkar notifications shown periodically in text, voice, or both. The app even reminds the user to praise Allah when the phone is turned on or off. The user can select the voice type and control the volume of all the prayers. The user can also determine the sleeping time to pause the reminder.

The app requires permission to manage phone calls to show the "Magles Thekr" reminder after each phone call. The app is based on a saying of the Prophet Muhammad that whoever sits in a gathering and indulges in idle talk, should recite the "Kaffaratul Majlis Thekr" before leaving the gathering. The prayer seeks forgiveness from Allah for any sins committed during the gathering. The app helps users remember this prayer and other Islamic prayers by providing automatic reminders.
