The frenzy of acquisitions in the mobile application analytics market may have started last year when Facebook acquired Onavo Insights, but over the past few months the pace of consolidation among those who collect and interpret data on all kinds of mobile apps has accelerated considerably. There was App Annie's purchase of its rival Distimo, for example, which happened in late May. Less than a month later, Yahoo said it would buy Flurry, another major player in mobile app analytics, for more than $220 million. More recently, advertising technology provider Tapjoy, based in San Francisco, acquired 5Rocks, a young startup in mobile analytics from South Korea. If this trend continues, it's going to be difficult for developers to keep track of where all the mobile app data is going and, more importantly, who's the best provider of services that will help them boost their businesses.
