User reviews

Stopped working after update

Icon looks different so I’m assuming app updated itself recently. I can longer open it. Crashes instantly.
Fix asap

Crashes on startup

App uselessly crashes instantly on startup. This means there is no way to access the settings of the brake controller and there is no way to access the emergency stop brake control button. This makes the brake controller extremely unsafe to use.

It’s ok but could be amazing

I use the app for the Curt Echo brake controller so my use is limited to that. Setup was easy and it does what it says. However it could be better with a few updates. It would be incredibly helpful if it had options to activate the various trailer lights by tapping a button. Making it easy to test brake lights, blinker, etc from behind the trailer rather than needing someone else to watch. As others have noted, there is no CarPlay integration. Sure would be nice if there was.

Disappointed

Developers did not take the time during beta to make the app work with the latest OS. Crashes on load.

Doesn’t Work

This app no longer launches on my iPhone 16 using iOS 26.6.1. I hope it still controls the brake based on the settings I set when the app did open. Even updated with the latest version of the app, still flashes a loading screen and then disappears.
