Fast Society pushed out a completely revamped iPhone app and an Android app will be coming out late as well.
The app is a vast improvement over the previous version. You can create up to five temporary or permanent groups with up to 25 people in each. The app let's you chat, add photos inline, initiate conference calls, or share your location. Fast Society also offers some unique features such as the ability to record a short audio "Shout Out" like a group voicemail that gets sent right into the stream. It also lets you distinguish on a map between where you're and where you want to go.
Creating a new team is easy with the "rally" feature that sends out a prompt to everyone in an existing team. You can also share an invite out via Twitter or Facebook and then only let in the people you want to hang out with. There is also an archive feature, which lets you relive past group texting moments with your friends.
