Dear HN,<p>My friend and I are currently developing an app to track and optimise wellbeing. We're looking at nutrition, supplements, nootropics and exercise. My background is in machine learning so the idea is to take a data-driven approach.<p>In case this app would be relevant for you: What features would you like to see?<p>If you're interested in trying a beta version, check out https://fullspectrum.app
