Until today, people with iPads or iPhones could use Amazon’s Kindle app only to read e-books. But a newly released version 2.9 of the app adds access to the over 400 magazines and newspapers that are available on Kindle Fire through Amazon’s Newsstand. This enables iPad users to opt for periodical subscriptions through Amazon instead of through Apple’s own iTunes Newsstand.
Apple still holds a couple competitive advantages: Its rules require Kindle app users to make purchases on Amazon.com instead of directly through the Kindle app, and the Kindle newspapers and magazines are mostly print replicas, while the Apple versions are actual iOS apps that may have unique features. Still, Amazon’s move introduces some healthy competition that should benefit Apple device owners, and offers publishers another avenue to reach them. Both Amazon and Apple keep about 30 percent of revenue from sales.
