Ask HN: Best realtime mobile analytics with API

I want to track in realtime some very simple, but accurate stats about the mobile users of our website. I want to know all the usual stuff like visitors, referrers etc but also things like hardware, screen resolutions of the mobile devices.

I know about the usual suspects like getclicky.com but wondered if there were any out there built from the ground up for mobile that addressed more efficiently the issues effecting analytics on mobile.

My last requirement is that they have an API so I can pull the stats I'm interested in into a dashboard.
