InstaTool

If you want to know if someone unfollows you on Instagram, if the overall views of your stories go down or if you gain more followers than you lose, InstaTool is the perfect app for you. This app will tell you all those tiny details about your account to help you improve your posts.

This app offers you tons of information to help give you an overall idea of everything that happens with your Instagram account. Here's some of the information you'll find in InstaTool: the total stories that you currently have posted, the number of people who have seen them and the average number of views that you have. Also, you'll be able to check the followers you have gained since the last update of your statistics and those you have lost. Lastly, you'll be able to see all the users that you follow but don't follow you back and vice versa.

Although InstaTool doesn't offer detailed statistics, it does serve as a way to instantly find out who's unfollowed you and figure out how your stories are being received.
