No, it doesn't have anything to do with Windows 10.
Arrow Launcher is a basic and user-friendly Android launcher with three main pages, and as its name suggests this is an early version of the product.
Your home page contains all of your apps. It’s divided into a Recent section, displaying the ones you recently downloaded, and a Frequent section, showing the apps which you use most often. Swipe to the left of the home page to find your phone and email contacts, which are also organized by frequent use. To the right of the home page are your notes and reminders, a valuable feature that isn’t included in most Android launchers. Swipe up for a list of quick-access apps, settings, and feedback options.
Arrow Launcher is currently in private beta. In order to access it, you need an invitation, which you can ask for by joining this Google+ group. However, you may want to keep in mind that, as with any other product that’s undergoing beta-testing, Arrow Launcher does come with some bugs: the row of apps on the bottom of the home page may be cut off, the Frequent sections on the home and People pages take some time to settle in accurately and, as of yet, the launcher does not support widgets. If you think you’re strong enough to endure all that, you can request an invitation to access it by joining this Google+ group.
