    1. *Update* Which wearable has the "most accurate" sleep tracking? (Apple vs Oura, Fitbit, Whoop, and Garmin across 14 sleep lab studies)
    2. Refining a personal wellness tracker (currently a google sheet)
    3. Sick of $10/month "biohacking" apps? I built a free open-source Android app that does the same thing (and better)

    1. I built a free tool that measures work-life balance, sleep, and productivity - then gives you a 10-year projection.
    2. Oura doesn’t expose Daytime Stress data in the API, so I built a screenshot‑based extractor
    3. I built a public health dashboard for my personal website
