We only use Localytic's analytic product within a number of our games. Their web interface provides an analytics self-service interface which allows product teams to answer many of their questions on their own without the need for SQL. This also allows them to refine their questions before they come to the data team with requests for more in-depth analyses.
One complaint is that Localytics has positioned their products more for e-commerce and other non-gaming apps. As a result, their SDK support has been lacking for our use in mobile gaming.
