The official Peach for Android is out today... there have been some unofficial clients built previously...
Personally I've stopped using Peach and dropped off relatively quickly to be honest. I'm not a big poster anywhere except for Twitter, although I love the idea of "Magic Words" and what they can be used for.
From the email they sent out, it looks like people really wanted Peach to work more like Twitter with a top request to follow others and have public profiles. That's a very different dynamic than "A place for friends".
