Tanda Menjelang Kematian is an Android app designed to provide information about the signs of approaching death. The app is based on the book by the same name written by Ustad Yusuf Mansur. The book talks about the signs that a person may experience 100 and 40 days before their death.

According to the author, the signs include shivers and strong vibrations throughout the body, which can be felt from head to toe in the evening after Asr prayer. Those who understand the significance of these signs will feel a sense of peace and beauty in their hearts, while those who do not comprehend their significance will feel no impact. This app is an excellent resource for anyone interested in learning more about the signs of approaching death and their significance in Islam.
