The app keeps crashing – iMetric Analyzer for Instagram Review

I don’t usually pay for apps like these because they usually never work as they say they will. I decided to give this a try and behold, the app keeps crashing as I try to unfollow people who aren't following me. I haven’t been using the app for long but tha really discourages me from using it further. What’s worse is that I paid to have all the the premium features and now the app keeps freezing and shutting down.
