disregard the 1 star reviews from people without FMC credentials. the average person doesn't have the physical piece of equipment to go with this so it's not going to work for them or they think they are a mechanic and want to be able to scan their vehicle. here's an idea most new Ford's have connected vehicle and you can login to your account and see all the info from the vehicle that way. if you have FMC credentials then this app works great! if you don't then it ain't for you.

useless app. won't work, can't even log in to the account. doesn't state that a paid subscription is required upfront. without logging in, getting a subscription is impossible. Customer service never responded to my email.

Dissapointed in this APP. It needs the Command function. Such as rad fan control, A/c clutch control etc. Its too basic of a tool. Its really only good for reading and clearing DTCS on the go.
