Not at the moment but it can be done I think. Normally the open app button is on the official kickstarter so I suspect a bug. I will investigate and keep you informed.
But I fear that if it opens the kickstarter app it will be annoying to come back to zerobox. Why would you prefer to open the kickstarter app instead of having the web page ?
It uses the default browser, which in iOS is Safari. I don't prefer Safari.
I don't like the idea of entering my KS credentials because I'm not sure if your app can strip that data? I'm pretty ignorant on this though.
I'd prefer to use your app to notify me of things, and then use the KS app to manage my interactions with the project.
