||GroupMe is the easiest way to start conversations and keep in touch with your real life network.
It's totally free, and it works on every phone. With apps for iPhone, Android, BlackBerry, and Windows Phone 7, as well as full support via SMS*, you can connect with anyone you know at any time.
-Start groups with the people already in your contacts.
-Send and receive messages using your data connection, so iPod touches can join in on the fun.
-When you have a poor connection, the app can switch you to SMS so you'll never miss a message.
-Share photos within any conversation.
-Every group gets a unique phone number.
-Any group member can call the number to start a group conference call.
-Ask a question to spark a conversation.
-Plan a night out with friends, see who else is around, or just talk about the game on TV.
-Direct it toward a few friends, or send it out on your social networks and see who responds.
-People you ask can comment without joining—it's fluid, lightweight, and fun!
-Take your private conversations aside.
-Like a free text message, without ever leaving the app.
-Add your location to any message you send.
-See all group members on a map.
