Wow. Is it possible nobody thought of this already? This seems like an extremely excellent no-brainer of an idea.
We think so : ) Do you have an app that needs this? Can you say a bit about your needs?
No; we assess other people's mobile apps for security flaws, and I'm pretty experienced with ObjC, but I'm coming from a place of "having gotten lots of value out of Olark, and seeing how that feedback loop is even harder to get on an iPhone than it is on a web page".
+1 for Android support!
We're planning on making it completely cross-platform. iOS to start though. Thanks for the feedback!
