While Microsoft is still officially working on the mobile version of Windows 10, it’s no secret that the company has all but given up on building its own mobile ecosystem. That only leaves Microsoft with one option: concede defeat and bring its applications to the likes of Android and iOS. That’s exactly what the company has been doing for the last few years and today the company announced that its Edge browser (the successor to the much — and often justly — maligned Internet Explorer) will soon come to iOS and Android, too. The company is also graduating its Arrow Launcher for Android and renaming it to Microsoft Launcher.

Even though Microsoft basically doesn’t play in the mobile OS and hardware space anymore, it still needs to have a presence on rival platforms if it doesn’t want to risk losing its relevancy on the desktop, too. Edge and the Microsoft Launcher are both key to this strategy because they’ll help the company to extend the Microsoft Graph even further. The Graph is Microsoft’s cross-platform system for allowing you to sync the state of your work and documents across devices and the company sees it as key to the future of Windows.
