Nfs heat studio

NFS Heat Studio was shut down not too long ago

if you want to know what Heat studio was it was basically a free mobile app you could use to customize your cars on the go, once done customizing you could connect to the app and port your build to the main game 

it also had an augmented reality feature, but at the end of the day it wasn’t that handy since you could just spend as much time customizing in game as you would on the app
