A vegan diet is often cited as the single easiest way to cut down on your environmental impact as an individual.

The problem with making these changes is that it's hard to see just how much of a difference you're truly making - that's why I decided to make Leafy, which will show and update you on how much your diet has helped. Figures are taken from the latest studies and will be refined as more research is done.

The app is completely free and can be used for both vegan and vegetarian diets.
