How many lives can you save?

Context

Planning a health campaign or behavior-change intervention? This interactive calculator guesstimates how many deaths or DALYs you might prevent in a year, using public-health data and the parameters you choose — region, disease, behaviors, and nudge type.

I built it at Duke as an R Shiny app backed by my better package. Pick settings on the left, explore the guesstimate and confidence interval, and use the tabs for explanation, stats, and package details.
