Problème

L’application ne veut pas ouvrir, je clique dessus et rien ne se passe

App keeps crashing!

Not having the app make the brake controller completely useless. Our trailer brakes locked up due to not being able to control through the app. What a waste of money.

Last update won’t allow me to connect to brake controller

The last software update made it so my phone cannot connect with my Echo brake controller.

Therefore, I cannot use it for added brake control for emergency braking of the trailer. Disappointed that it won’t work now. I even deleted the brake controller and re-paired it and also uninstalled the app and re-installed it. Neither attempt at fixing it worked for connecting to my brake controller.

Unusable App Since Update

The app no longer allows adjustment of the Max Output for my Brake Controller. It was fine before the most recent update, but now the confirmation button is offscreen due to improper sizing. Please Fix!!!!

Can’t set brake levels.

The original version of the app worked but things have gone downhill since they were bought.

I cannot set the brake levels. I can get tot the screen to adjust them, but there’s no way to save the settings.
