## What is OneControl Auto?

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 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.

### 1/5 — Crashing on opening

*2026-08-25*

After updating I can’t open the app it crashes. I need my brakes

### 1/5 — App won’t open

*2026-08-22, version 2.1.0*

It flashes and closes. Fix it!

### 1/5 — Unusable

*2026-08-21, version 2.1.0*

The app update is horrific. I can no longer toggle the controls for my breaks because the save button is below what is accessible on my phone screen.  Scrolling does not help, nothing on this new interface will work for the breaks. This is incredibly dangerous, and I’m starting to wonder why I paid money for this awful safety hazard.

### 1/5 — Suddenly will not run

*2026-08-21, version 2.1.0*

App quits instantly upon opening. No update, no workaround, just disconnected brakes. Thanks.

### 1/5 — Junk

*2026-08-21*

Crashes on opening ..bring back Curt!

### 1/5 — App won’t open

*2026-08-20*

App crashes every time since the latest update. This happens on iPhone 13 Pro and 14 pro max. Please fix!
Sure wish I could use this app! Horrible!

### 1/5 — Miss the old version Curtis

*2026-08-18*

Nothing but issues since it was taken over and this version never works ???

### 1/5 — Doesn’t work

*2026-08-16*

When it was the old app, I had no issues. Now I can’t set anything, because the screen doesn’t scroll down to hit an ok…and when I hit the back button, it doesn’t change the settings. So now when I touch my brake pedal, I get full brakes on my trailer. That seems really safe. Can we go back to the old Curt app please.

### 1/5 — Junk

*2026-08-15, version 2.1.0*

The app will not open lashes and closes. It’s worthless.

### 2/5 — Accès à l’option apply pour modifier les paramètres

*2026-08-15*

Pas capable avec mon iPhone 16 pro
