In a surprise announcement, Microsoft said its Edge web browser is now available for iPhones, with a release for Android "in the coming weeks." The initial rollout for the browser will be limited to those in the U.S. but should expand to other markets over time. Currently, the browser is in preview only as Microsoft begins to build out features based on user feedback. The same goes for tablet support on both OSes, which should come later.

Edge for iOS, Android and 'Continue on PC' Microsoft's main goal with the Edge browser for iPhone and Android users is to make sharing documents easier and help you pick up where you left off when using Windows 10.

Part of the Windows 10 Fall Creators Update feature set is the ability for consumers to pass a link to the "Continue on PC" share target. While that feature works, it is hard to find and not very intuitive.

Edge for iOS and Android – Slightly more than skin deep Microsoft told Windows Central that these are not native browsers in the traditional sense. Edge for iOS is based on the WebKit layout engine, while the Edge browser for Android is based on Chromium. That rendering technology contrasts with the EdgeHTML engine that the Windows 10 browser leverages, so build strings and feature sets won't be aligned.

Apple simply does not allow third-party browsers based on non-WebKit engines in the Apple Store, and Android is built around Chromium, making it a more natural fit for that OS. These Edge browsers are basically sophisticated skins with advanced feature sets that allow syncing with your Windows 10 PC for favorites, reading lists, reading view across your PC and phone, and more features that are familiar to Windows 10 consumers. Due to Apple's restrictions, consumers won't be able to set Edge for iOS as the default browser. Such limitations, however, do not apply to Android.
