TrenChat

TrenChat is an interesting tool for anyone who travels via train or subway and has a long and boring trip to look forward to. With this application, you can chat with people in the same situation as you – passengers on your train who are bored on their commutes.

This application gives you a direct and totally random connection with other users. Just enter your name as you want other users to see it and select whether you're traveling via train or metro. Then start talking with random people around you.

The search feature takes a little time depending on how many other passengers are also connected. Once you start chatting with people, though, you can skip people you want don't want to talk to until you find someone to hold a conversation with. The other users will see your name in the same way you see theirs.

On the other hand, once you're in a private chat with a user, you can send text, photos, emoticons, and documents, just like any other messaging tool. You can also change the background and save your username so you can always use the same one when you open TrenChat.
