Unlike Facebook where both parties are involved in forming a ‘friendship,’ Instagram takes a one-way approach where one person can ‘follow’ another person without the latter following them back. While this implementation has its advantages and disadvantages, one bit can be particularly annoying with it – 'unfollowers' or those who have unfollowed you. Since Instagram offers no built-in tool to detect 'unfollowers', users are often left scratching their heads, wondering who unfollowed them when the followers count dips unexpectedly. If you happen to be one of those then we’ve got you covered here. The easiest way to find your 'unfollowers' and then return the favour of unfollowing them is by using a third-party app so that you don’t have to trouble yourself with doing it manually. The latter can be a very cumbersome process if you’ve got a lot of followers. There are a lot of apps available on the Play Store and App Store for this purpose, but we recommend FollowMeter as it's easy to use and has got a super-polished interface. Disclaimer: Sharing your Instagram credentials with a third-party application allows access to your account to said application. Proceed at your own discretion. Track your unfollows using FollowMeter You need to first download and install FollowMeter on your iOS or Android device. Setting up the app will require you to log in to your Instagram, which you can proceed with after tapping the “Login” button. You’ll be directed to the app’s main page then, where you’ll see a number of options to manage your followers. Normally, you’ll be able to track unfollows using the “Unfollowers” options but first-timers will need to visit the “Not following back” option to catch those who have stopped following you. However, if inputting your Instagram credentials into a third-party app bothers you, then there's another, manual method. Sieve out unfollowers manually By checking your own Followers list: Open Instagram and head over to your profile using the icon located at the bottom-right corner of your screen. Near the top, you’ll see a “Followers” option, tapping which will open up a list of all the people that follow you. Using the search bar, type in the name of the account you think might've unfollowed you. If their name doesn’t pop up then they’ve unfollowed you. If you’re unsure about the name, simply go through the list to find the user. By checking the following list of the other user: Alternatively, if you’ve already got someone in mind, you can simply use the search bar to find them. To access it, you’ll have to tap the search icon which can be found at the bottom left, on the right of the home button. Input the name of the account you wish to check. Go to their profile and tap on the 'Following' option. If your own name appears on the list then they’re following you. If not, then either they unfollowed you or they never followed you in the first place.
