Every day we use 2000 dollar computers to build and test our apps. However, it has been shown that the next billion internet users will access our apps through low end devices with lots of limitations. They are on remote places of the globe, they have accessibility restrictions and devices with limited compute power and slow connection speeds. In this talk we will reflect on how to build and test apps that can be used by everyone and not just a few.
