This might seem like a niche app (and it probably is), but because there aren't so many apps in the Market for this, Campyre is worth a mention. If you've ever needed to hop into a Campfire chat by 37signals, you'll know what I'm talking about.
Campyre is a third-party Android client that lets you log in, read, and post in a Campfire chat. It's ideal for those times you're out and about but need to stay connected to the people you collaborte with.
Signing in is easy; it only requires you plug in your chat room's custom Campfire URL, your username, and your password. From there, you'll be presented with a list of rooms you can join. Tap the one you want to hop in, and boom, you're in.
Once you've joined a room, you'll be able to see all the stuff folks are saying as well as post your own messages. There's timestamps for when people join and leave, but you can turn that off in the settings. You can also check out today's transcript in case you think there's something you missed from earlier (when you were unplugged).
There's a fairly bare settings menu, too. You can change the maxmium number of messages the room will show, and enable or disable enter and exit messages along with timestamps.
A pretty worthwhile feature is the "create shortcut" option. If you choose this, Campyre creates a shortcut to the room you're in on your main homescreen, so you don't need to deal with logging in and selecting a chat room anymore. Simply tap your shortcut and you'll go straight to the chat.
Campyre is completely free (and without ads, to boot), so if you're a frequent user of Campfire in the web browser, Campyre is something definitely worth checking out.
