If you like how the Windows 10 Lock screen looks and feels, then you’ll probably enjoy using a jailbreak tweak called Ventana by iOS developers CoolStar and Jeremy Goulet. This tweak redesigns your iPhone or iPad’s Lock screen to make interface elements appear more as they would on a Windows 10 device.
Right out of the box, Ventana themes the Now Playing interface, any incoming notification banners you might have waiting for your attention, and the date and time display. Ventana also provides you with a Siri shortcut akin to the Cortana shortcut that you might find on Windows 10.
