I was doing F4F (followback) and following churn to increase following on Instagram now I want to massively unfollow 3/4 of those I followed. One aspect is anyone who hasn't posted a picture in a month as they don't care if I unfollow since I'm not following anything. Are their any apps that just list users who haven't posted for a while? I saw a few related questions here recommending IGExorcist but that's to kick out inactive followers and I want to get rid of inactive following (not followers). I don't care that much about engagement rate which is why you get rid of followers (I average 1 like per 15-30 followers per photo and post 5x a week). I've seen this available in a bunch of tools for Twitter but nothing for Instagram. Can you help? Thanks.
