You have probably heard about the homeless guy in New York City who wrote is own app? Leo Grand was approached by Patrick McConlogue (an app programmer) with two choices: Take $100 or an learn how to code. Grand chose to learn a job skill. The two met for an our a day for sixteen weeks using a couple of used textbooks and a refurbished Chromebook.
This is Leo Grand's app: Trees for Cars. Its a carpooling / ride sharing app. Simply sign in to the app and network with people who need or are offering rides. What sets this app apart from the crowd, other than getting tons of press because it was written by a homeless man, when you share a ride the app calculates the amount of CO2 you are saving and turns it into a competition between members...who can save the most CO2?
