Looks promising

James, this book wouldn't be possible without you. You taught me virtually everything I know about Xcode!

Yes you can by inviting people with our per room invitation feature. There will be a need to have chat room concept so people know what to chat on.

Cool, think you can get a lan based room going?

As others have said been keen to do something very similar. Glad someone got off their ass and did it.

I always envisioned it useful at parties and places where the internet may be too congested but the lan/wlan not so much: read conferences

It's through the internet

At least for now, it's not meant for private/sensitive messages.

We're more focusing on allowing people to join chatrooms which the location information are to help people easily find them, there's also an invitation feature to let you tweet your room and people can join all over the world.

Yes we hope it can be really useful, maybe for conferences and events, never know. We'll see how it goes :)

Right there's nothing to do with Ripple Labs, we named it through a hackathon before we found it out.

Thanks Orta you've been resupportive to us :)

Here's the direct link https://itunes.apple.com/us/app/ripple-chat/id787142731?ls=1...

Probably take some time for AppStore to process those keywords, stay tuned :)

Yes it's using the keyframe APIs, it might be more like an experimental code style for now, but we will keep revising to make it better.

There are so much awesome APIs on iOS 7 that we planned to leverage in the future, cutting off legacy platforms simply help us focus on looking ahead instead of backwards.
