HitchAngle: Makes backing with your trailer a breeze

The idea of HitchAngle was born when I started thinking about getting a backup camera for my travel trailer. There are hundreds of products on the market which basically consists of a camera (to put at the back of your trailer) and a screen to fit somewhere on the dashboard inside your car. All of these of course cost money, most require wiring for installation, and when they inevitably stop working, goes in the thrash to put even more strain on the environment. Also, none of them offer anything beyond a simple video feed, unlike factory pre-installed solutions from Ford, WV etc that also lets you see (and steer!) the trailer angle in your dashboard. HitchAngle makes it possible to use any old spare mobile device (which you most probably have lying around) as a 100% wireless backup camera and angle sensor, which, coupled with your phone inside your car will display the video feed and hitch angle overlay in the form of a beautiful heads-up display. I would love getting feedback (being new to PH, I'll make sure to give some too). Being a niche product, I am most concerned that no one (or very few) even understands what it is, and how it works. So please, comments on the landing page are welcome. And even if you don't own a trailer you are welcome to try the (free) app just to see what it does (preferrably using two phones, but one phone coupled with a computer browser will also do). Thanks in advance!
