Up until 16 weeks ago, Leo Grand was anything but, ahem, grand; living on the streets, no job prospects, and winter fast approaching. Then one day he was given a choice, $100 or an offer to learn how to code. Thankfully, he took the offer and now he's just released his very first app for iOS and Android. It's called Trees For Cars - a 99c carpooling app that's aimed at saving the environment and building relationships in your community, with all the proceeds going to furthering Leo's education. Fingers crossed it sells well.
