With this app, you can get a detailed report about your Instagram account - particularly your reach. It gives you a blow-by-blow account of your follower activity - including data on earned followers as well as lost ones.

In addition, you can get real-time notifications of follower activity - such as when you gain new ones, or lose one or two. This platform also gives you a list of people who do not follow you, as well as those whom you do not follow.

This app is free - but there is a Pro version that gives you full access to all features.
