About this app

Manage Your Trailer from the Palm of Your Hand

Take the helm and command your trailer from the palm of your hand. The OneControl Auto™ app works on Android or iOS smartphones and makes it easy to monitor and control your trailer as you tow. Simply connect the app through Bluetooth® and control your brake controller while monitoring tire pressure and preventing trailer sway. With OneControl Auto you can make changes while towing in real-time and even create and save profiles for towing specific trailers or payloads.

Compatible with CURT Tire Linc™ TPMS Monitor, Echo™ Brake Controllers & True Course Auto™ Sway Controller

Tire Linc allows you to monitor your tire pressure in real time while on the road and helps you to prevent over or under-inflated tires, which can quickly lead to a dangerous blowout. CURT Echo brake controllers feature Bluetooth™ connectivity and allow you to monitor and adjust your brake level output and brake sensitivity from your smartphone. CURT True Course Auto is an automated system that prevents trailer sway when unexpected events occur, such as emergency maneuvers, high wind conditions or when tire blowouts happen.

Note: Products sold separately

With OneControl Auto You Can Easily:
- Monitor trailer tire pressure
- Control trailer brake output and sensitivity
- Prevent trailer sway and avoid accidents
OneControl Auto™ makes it easy to monitor and control your trailer as you tow.

Had this controller for 2 years and worked great,then this year along come this upgraded version and now I can't adjust the brake settings so now it is set at 50 half of the 100 max settings, tried to adjust it down to 20 or 25, there is no button to apply so when I push the back arrow the settings is still 50. So now the trailer brakes lock up every time I apply the vehicle brakes, very frustrating.

I've used this app with my brake controller for several years, without any issue. now comes an update that causes the Bluetooth connection to fail when my phone is too far away. EACH time I have to remove the device, add it, and enter the pin. unacceptable. absolutely garbage products from the IT department. I have tried all the steps including another device, with the same results.

Had an echo brake controller for 2 years. The old app worked great, no issues. This new app is trash. We spent over an hour trying to get the app to connect, did all the toubleshooting steps, and nothing. Had to drive our first trip of the year without a brake controller. After the trip I called the customer service line to try to get help. They said an upcoming update would fix the issue. It's still not fixed - it at least finds the device now, but it won't connect, just sits in pending mode.
