Johnny's app recommendation is SkyZen. It was created by the International Air Transport Association, and supposedly helps with jet lag. It's supported by Jawbone, monitors your sleep patterns, tells you when to eat and what to eat, all to help you minimize jet lag.
Johnny's website recommendation is BonAppatour.com. This site connects you with local people, and for about $49 per guest, you can have dinner with them at their house. Locals can also sign up to host. Leo says that's a great idea, and he wants to do it.
Leo also tried SilverCar, which picks you up and rents you a brand new Audi S4 via an app. Leo says it's awesome and painless. Johnny tried it in Austin as well and they are growing all the time.
