I'm currently weighing my options, and all the popular ones (Mixpanel, Keen.io, and friends.) look quite good and polished.<p>I want to hear what you were missing in your chosen solution and what service provided a solution?
Flurry - good for demographics
Mixpanel - great for a) realtime, b) nice retention visualization, c) a bit expensive.
NewRelic - good at also giving visual indicators of api issues.
BugSense - also does analytics. great for bug reporting.<p>Haven't used google analytics on mobile much...<p>overall if you have to pick one I'd recommend Mixpanel
