SpanSignals
SpanSignals is a mobile + web app that estimates how specific habits and clinical markers affect your life expectancy and, more importantly, your “risk trajectory” over the next 5–15 years. It avoids feel-good guesses: you’ll get blunt ranges with confidence levels, and it will clearly label what’s unknown or low-quality data. Users connect wearables (steps, sleep), optionally import labs (lipids, A1c, BP), and answer a short lifestyle survey. The app then runs evidence-based risk models (e.g., cardiovascular and all-cause mortality proxies) and converts them into a simple dashboard: biggest risk drivers, what changes would move the needle, and what won’t. It also includes a quarterly “reality check” report that compares your behavior to your stated goals and flags when you’re drifting. This is not medical advice; it’s a decision-support mirror.
