App analytics firm Localytics said that “any Android developer with a focus on tablets should be distributing their apps in the Amazon Appstore”, noting that more than half of the Android tablets it sees in the US market are Kindle Fires.

According to the company, 59 percent of Android tablets using apps which include its analytics technology are in the US, with the share of the Kindle Fire in this market dwarfing that of devices such as Samsung’s Galaxy line and Google’s Nexus 7.

However, the Kindle Fire has a relatively limited distribution profile: 89 percent are in the US, with “most of the rest” in the UK – apart from these two, no other market has “even one percent” of worldwide Amazon tablets.

But this could bode well for the future, Localytics suggested.

“The degree to which Amazon has dominated their most serious geographical market should speak to the future potential, and since Google Play is unavailable on the Kindle Fire family, adding Amazon’s Appstore as a distribution channel is important,” it noted.
