Who Deleted Me on Facebook app has been released on Android and iOS, which allows users to keep track of their friends list.
According to thenextweb.com, the app is similar to Who Unfollowed Me for Twitter, which tells the users when friends have disappeared from their list and whether they have deactivated their accounts or actually deleted the user.
When the users download the app it will not show them friends who have deleted them in the earlier period. It only starts tracking from the time the user activate it.
Also, it shows the users their newest friends, people they have chosen to block and a 'last seen' stamp for everyone in their list.
The app used to be available on Facebook, but had to be removed in April this year after Facebook changed its policies.
In addition to on the phone, the users can also install it as a browser extension.
