It so good that once I updated it promptly alerted that I had a TMPS warning from OCTOBER 7. Two weeks ago. I knew my tires were borderline low and with cooler days coming I would need to add air. So I did sometime during the week of October 7. Never once did my truck warn me or give me a message, until today when I updated the app. It promptly made a noise and popped up the message from 2 weeks ago. Some day Ford you might just get ahead of this game, but not likely anytime soon.New version released this morning.
