Another awful article on math
The article is comparing numbers that cannot be compared. Rubin’s number is a number of Google Android activations. I’m not 100% the mechanics of what they track that but we have been told that these are carrier activations done in store, new devices only, and Google apps devices. Which mean that 3.7 million people went to a store on Christmas eve and day and bought a Google Android Device. (This number doesn’t include Kindle Fire or Nooks)
Flurry tracks activations by specific app installations. Flurry has “more than 140,000 apps using Flurry Analytics, Flurry detects roughly 100% of all new iOS and Android devices activated each day” “including top apps like Angry Birds, Skype, The New York Times, MTV, Hulu, Zynga, Yahoo!, etc” Which means that a device can not be tracked by flurry until one of these apps are installed. All those devices that were bought, activated, and wrapped before Christmas wouldn’t be counted until they were opened and an app was installed.
Flurry also tracks apps wherever an app is distributed, and the app developer has added us. Meaning Amazon apps store is included in these numbers. This also mean that all Kindle Fires, Nooks, iPads, and iPod touches are included in Flurrys numbers.
The main point I’m trying to make is that you canNOT compare Rubin’s numbers to Flurry’s. Rubin’s number is all about Google accounts being asscociated with a Google Android mobile device and Flurry’s is about installing an app on a new mobile device. They track completely different metrics.
