Tracking mental acuity and cognitive performance

Hi everyone! Would love your guys' input on something I'm working on. Think of it as a "Strava for Cognition" - essentially using voice analysis to measure mental acuity, cognitive stress, speech clarity, and more. We want to provide people with a more continuous and objective way to measure cognitive changes and relate it back to other health trends + lifestyle habits. We're looking for early users to test and help shape the product. Sign up here if you're interested! https://airtable.com/appczl6TRhOwcUBKu/pagz9QaSGqFqK9evY/form

Would also welcome any thoughts/suggestions on this and how you would use it!
