Need Feedback On Instagram Follower Web App

I've created this web app that helps people find users who will follow them back in Instagram with 80% accuracy.

This app is for people who prefer to use follow backs to increase their following. An additional advantage is that you can find followers for various specific niche.

There's no signup process. It gives you a list of accounts that you can copy and then follow. You can visit the app here: (the rest of the website is still WIP): https://www.influrocket.com/instagram-follow-back-tool/
