Frequently asked questions

How does it work?

By fixing a mobile device (for example, an older phone you're no longer using) in/on your trailer. By using its camera and rotation sensor, a video feed and hitch angle visualization can be displayed on another phone/tablet (the vehicle HUD device).

Is it accurate enough?

Most mobile devices from the last couple of years have a gyroscope and an accelerometer. These two sensors combined makes a fusion sensor that outputs absolute rotation for the device with very high accuracy.

Wait, my phone has a compass, why won't HitchAngle use that?

Mobile compasses aren’t very accurate and are also susceptible to electromagnetic disturbances. It is not unlikely though that HitchAngle will make use of compass data for calibration or alignment purposes.

How do the two devices talk with each other?

A direct communication channel is established between the vehicle and trailer device by a technology called WebRTC, which makes it possible to transmit video and data with low latency.

Do I need a data plan for my trailer device?

No, just turn on internet sharing on your vehicle HUD device and tether your trailer device to that.

Why do I need to log in to use HitchAngle?

It enables the two devices to find each other automatically.
