A FIRST LOOK AT EUROPE’S ALTERNATIVE IPHONE APP STORES

Summary from the TLDR newsletter

There is currently only one third-party iOS app store live in Europe. Other app stores have been announced and some are in the review process. One reason for the lack of alternative app stores is due to Apple's Core Technology Fee, which requires developers to pay Apple 50 euro cents for every annual app install over one million, with third-party app store developers paying the fee for every first annual install of their app marketplace. Apple has also made installing third-party marketplaces a hassle, requiring around a dozen screen interactions to install each store.
