Displaying information within customer account when logged in

Hello,
We’re looking for advice, and suspect the answer is an app, so we welcome recommendations.

We are building a calculator where a customer completes a series of survey questions and is given a ‘report’ with nutrition advice and some product recommendations.

How are be able to display these reports (or at least a link to the report) when a customer logs into their account? Probably an app!?

Looking forward to some advice/help.
Many thanks,
