Add Months

Add Months Identify the single change most likely to extend your lifespan. Add Months is a private, analytical tool designed to answer one focused question: which behavior in your life currently has the greatest impact on your expected lifespan? Instead of overwhelming you with scores, streaks, or endless optimization advice, Add Months analyzes a concise set of demographic, health, and lifestyle inputs and identifies your Dominant Challenge — the factor offering the largest potential gain if improved. The app uses conservative population-level risk modeling to estimate relative lifespan impact. Results are presented as ranges, not guarantees, and are intended to provide clarity and proportion rather than alarm or motivation tactics. You’ll see: • Your Dominant Challenge • An estimated lifespan gain range if improved • The next largest opportunity if your primary factor were addressed The goal is simple: focus attention where it matters most. Add Months is not a habit tracker, coaching platform, or social network. There are no streaks, no points, and no behavioral nudges. You can re-run the analysis anytime your life changes. Private by design • No account required • No ads • No analytics tracking • No cloud storage • Encrypted local data • Hard delete means permanent deletion Your inputs remain on your device. Add Months is provided for informational purposes only and does not constitute medical advice. Always consult a qualified healthcare professional before making health-related decisions.
