Inspired by Charles Darwin, and brought to life by Chris Darwin, his great-great-grandson, The Darwin Challenge App tracks the days you don’t eat meat, and shows you the difference you make.

From improvements to your health and wellbeing, to animal welfare, human rights, and the world, you’ll be amazed by the benefits of going meat free, just one or more days a week.

Vegetarian or Vegan? Download the app to see the difference you’re already making, connect with people just like you, and spread the word.
