IG Tool for Tracking Metrics

Is there a tool available where I can track the metrics of ~50 accounts, like daily follower growth etc - importantly they wouldn't be my accounts, but any public accounts. Then I can download a spreadsheet of data from last months, etc. Any tools like this exist?

Try https://igblade.com/ , you can add and follow the growth of any account from the day you search them on the website, and you can also save them so they will show up all in one page when you visit igblade, but you must sign up i believe to be able to favorite many accounts in one page to see their growth and it's for free

Owlstat, ninjalitics are good tools. The premium versions can help you more than free ones but at least you can test it out

Thank you! I'll do an analysis of them. Great to find a few that exist. Do you guys use these for work?
