GroupMe is the best way to chat with everyone you know. It's absolutely free, whether you're talking to a group of friends, or texting with one person. Best of all, it works on nearly every phone, via push or SMS. With GroupMe, it's easy to reach anyone, anytime, anywhere. It's like a private chat room for your small group. Have as many as you want, and it's always free. Now, you can coordinate with coworkers, organize a game night, and keep in touch with family all in the same place. With native apps for iOS, Android, and Windows Phone, you can chat with your friends from your phone on the go, on your computer at the office, and on your tablet from the couch. You can use GroupMe to split costs and collect money from your friends. Not every message should go to the whole group.
