حدث في مثل هذا اليوم is an Android application developed by AnarchyDev Official. The app provides information about historical events that occurred on the current day. The app relies on Wikipedia to gather information and does not require an internet connection to work.

One of the app's main features is the ability to send a daily notification to the user, showing the events of the day. The app also allows users to choose a specific day and view the events that occurred on that day. Additionally, the app allows users to copy and share the text, as well as change the font size.

Overall, حدث في مثل هذا اليوم is a useful application for those who are interested in history and want to know what happened on a specific day. The app is easy to use and provides accurate information. However, it would be helpful if the app included more sources of information besides Wikipedia.
