Why spend several hundred dollars on a Heads-Up Display when you’ve already got one in your smartphone, minus the actual glass? That’s the driving factor behind Hudway Glass, an inexpensive accessory that transforms your smartphone into a HUD. The secret of Hudway is in the multilayer glass that’s built from plastic and optimizes distortion-free transparency while maximizing reflectivity from the smartphone below. Stick it to your dash using one of two included mounts — one low profile and another more adjustable one — then flip it open. And using it is as simple as firing up a HUD-supporting app on your smartphone — such as Hudway’s own GPS navigation app, Speedometer, Navmii, Baidu Maps, and plenty more — and then placing it on the non-slip cradle.
