Show HN: A Phenotypic Age Calculator

Hi HN community, are you younger than your chronological age? I created a simple calculator where you can enter your biomarkers from a common blood test and see your actual biological age or "phenoage." The enhanced report includes your percentile compared against peers born in the same year, detailed explanations of each biomarker's importance, and recommendations for improving each.

I would welcome feedback on anything and, if anyone ends up buying the report, would love feedback on that as well, or thoughts on upgrading the pdf formatting. I ended up using node express server and the following apis: stripe, sendgrid, google cloud storage, and openai although currently not using openai for anything but might be cool to add for personalized health recommendations? Let me know what you think,

Best, Adam P. Ohio
