JoinMe for Stanford makes it easy to spontaneously hangout with your friends. Tell them what you are about to do, and if they are free to join they can simply show up! It is about being laid back, and not having to plan your day.
The best days are those when you just so happen to run into a good friend. On a whim you decide grab lunch, catch up, and are reminded of how wonderful they are. JoinMe helps foster these moments with every event you create.
