Safari has a new Smart App Banner feature in iOS 6 and later that provides a standardized method of promoting apps on the App Store from a website. Smart App Banners automatically determine whether the app is supported on the users device. If the device loading the banner does not support your app, or if your app is not available in the user's location, the banner will not display.

Is it possible to add this meta-tag to Piwik? <meta name="apple-itunes-app" content="app-id=737216887" />
If a user opens the Piwik installation within iOS 6 / Safari Browser, he'll get a notice that there's an iPad app.
Later we could possibly also add "app-arguments". But I don't think Titanium supports that. Arguments allow us for example to pass the currently opened report and siteId to mobile app. Mobile App would then open same report/website as user had opened in Browser.
Looks like a nice idea and possibly useful :)
I'll move this to Piwik 1.10. Feel free to move it back to Feature Requests if this is not ok.
