This tool can calculate the total sum of likes, plays, watch-time, etc. on all your Instagram posts over their entire lifetimes!
This tool uses Facebook APIs and all you need to do is:

• 1) Create a Facebook Developer account and application. [Instructions here].
• 2) Enter your newly created Application ID in the form below.
• 3) Log into Facebook using the button below.
• 4) Create/associate a Facebook page with your Instagram profile.
• Required to use Insight APIs; instructions will appear in login popup window if not done so already.
• 5) Log into Instagram inside popup window.
• 6) Follow instructions to grant this tool permissions to view your insights.
• I specifically request for the following permissions: [instagram_basic, instagram_manage_insights, pages_read_engagement, pages_show_list, business_management], as they are required by the Insights API here.
• 7) After the window closes and returns to this page, click "Calculate my Insights!"
• 8) Wait for the page to finish calling Facebook's API's for all your posts, then display the results in a table in this window!

Results can also be downloaded as a .csv file!!!

This tool also only works for public Instagram profiles that are associated with a professional Business or Creator account.
...and so if that sounds like you, please enjoy this tool!
