We are currently using Flurry basic version mainly because it's free and really easy to setup. I recommend it for those two reasons.
We are also planning to use Appfigures real soon for iTunes Connect download analytics (http://www.appfigures.com)
Also, I see Localytics as another option. Anyone have any experience with it?
in-app Tending to use Flurry because of ease and in house stat tracking due to custom requirements
Make use of AppViz and appannie for download + store monitoring
