TimeTradeoff

TimeTradeoff is a mobile + web app that turns long-term time horizon thinking into concrete tradeoffs. You set a few life “tracks” (healthspan, finances, relationships, skills, freedom) and define what “good” looks like in 5, 10, and 20 years. Each week, you log a handful of real decisions (late nights, workouts, spending, learning, social time) in under two minutes. The app then visualizes how those choices shift your projected outcomes using simple, transparent models (not magical predictions). It highlights the highest-leverage habit changes and shows the opportunity cost in time: “This pattern likely costs ~8 healthy days/year” or “adds ~3 months to financial independence.” It’s intentionally blunt, with uncertainty ranges and assumptions shown, so users can disagree and adjust. The goal is not perfection—it’s fewer self-defeating defaults.
