This had been a great app. I had it with my 2015 Silverado and it was free to use. I occasionally used the remote start feature once or maybe twice a month. I traded my 2015 Silverado in for a 2018. I got one free month of the apps remote start feature, now they want you to pay $15.00 per month for it. I go a promo email to use it for $11.99 per month. I think it is a rip-off. Chevrolet taking advantage of its customers and abusing them with ridiculous overpriced features. It’s a one time fee app at best. Don’t fall for their antics.
