CalcReports for Instagram is a free iPhone app developed by Wuhan Xiaolong Technology Ltd. It falls under the category of Utilities & Tools and offers a range of features to enhance your Instagram experience.

With CalcReports, you can view Instagram stories anonymously, perform a full analysis of your stories, and easily mass follow or unfollow users. The app also allows you to find users who don't follow you back, giving you valuable insights into your Instagram followers.

Using the app is simple and intuitive. Just navigate to the report page you're interested in, select the desired data range (with unlimited count support), and click "Start Refreshing" to view the results. The app accumulates data over time, ensuring you have access to comprehensive historical data for comparison.

CalcReports also offers a calculator page where you can compare all your historical data. If you're curious about mutual friends, you can select "following" on the left and "followers" on the right, choose the desired time range, and click "Intersection" to find users who are both your followers and whom you follow.

The app provides an excellent platform for creating various reports and unleashing your imagination.
