Hudway app delivers windshield HUD for driving

Free iPhone app provides an augmented-reality head-up display (HUD) for driving by reflecting it off your windshield.

After Garmin released its $129.99 HUD gadget in July, it was only a matter of time before something similar landed for smartphones.

Hudway is a free iPhone app (coming for Android by February of next year) that reflects driving directions onto your windshield for low-visibility conditions.

It works off the back of Google Maps. You build a route on the map, which the app then preloads so it can be used offline -- useful if connection is intermittent or you don't want to use data. You then place your phone on your dashboard (we recommend securing it with some kind of mount or Blu-tack) and driving directions are displayed reflected off the glass.

This is the app in its basic form. Upgrading to Pro for $1.99 will allow you to customize the view of the road and its turns, and dangerous sections of road will be displayed in red.

We imagine that it wouldn't work particularly well in bright light, and the app's developer is very careful to specify that the app has been designed with low-visibility conditions in mind.

"Usually, we like to drive -- it's convenient, fast, and fun. But when it's heavy rain, snow, foggy conditions, or just a dark night, driving can be very dangerous," the app's description reads. "And this danger is due to very limited visibility of the road, usually 20 to 50 meters (60-150 feet) ahead. There might be a sharp turn or just straight way."

So it won't be replacing your GPS any time soon, but for a maximum of $2, with no need to buy extra map packs, it's a pretty sweet deal.
