My Statistics - Social Tracker is a free iPhone app developed by Kiril Georgiev. It falls under the category of Social & Communication, specifically social networking.

This app provides detailed statistics about your profile on Instagram or Facebook, depending on the account you use to log in. With your Instagram account, you can track stats such as non-followers (people you follow who don't follow you back), fans (people who follow you but you don't follow back), and any changes in your followers or who you follow. Additionally, you can identify your most active followers based on their posts, comments, and likes.

If you use the app with your Facebook account, you can track changes in your friends list, including new friends and lost friends. You can also monitor the active status of your friends' profiles, including deactivation and reactivation. The app even provides a list of all deactivated profiles at the time of sync. Similar to the Instagram feature, you can identify your most active followers based on their posts, comments, and likes.
