Microsoft has already courted Android fans by releasing a lock screen, but it's taking the relationship one step further by introducing a full-fledged launcher. The newly official (if already expected) Arrow Launcher is a purposefully simple interface that centers on your favorites. Your home screens include both everything you've used recently as well as your most commonly-accessed apps and contacts -- it's a bit like iOS 9's Proactive feature writ large. You also get a tray for quick access to key apps and settings (see above), not to mention tightly integrated reminders. This is one of Microsoft's numerous Garage experiments, so it's tough to know how much long-term support it'll get. Still, it's worth trying if you've ever wished that Microsoft would make an Android phone beyond the short-lived Nokia X.
