Dayfinite: How long might you live? Find out in 5 minutes

A few-minute quiz that estimates how long you might live, based on your lifestyle and UN population data. It shows which of your habits are pulling your estimate up or down, with detailed, practical tips for each one and links to the research behind them. Your report also compares you with people your age in your country, shows how changing a habit might shift your estimate, and includes a scenario for future medical progress. No sign-up, available in 7 languages.

Hi Product Hunt! 👋 Dayfinite is a quick tool to estimate your life expectancy.

Yeah, I know — you’re probably rolling your eyes. Nobody can actually predict a lifespan, and you’re completely right. But that’s not really the point.

As a programmer who sits at a desk all day, back pain became part of my daily routine. That was my wake-up call, and it inspired me to build this — a way to reflect on daily habits and see which ones are pulling your estimate up or down.

The goal is simply to nudge us to pay a bit more attention to our bodies, not to predict the future.

The quiz is free; your full personalized report is a one-time $2.99, about the price of an espresso. ☕

I’d love your honest feedback！
