Looks like it does a lot more than coach you on fuel economy. It reads fault codes, and even lets you clear them. It apparently also calls 911 if there is an airbag deployment, like OnStar does.
Personally, I do care about my gas milage, because I like to keep my money in my pocket. But, the other features interest me more than that one.
Have one. Worked on my Passat but seems to not register trips correctly when set up for my Mini. Android app for it is very finicky. It gives you some extra data connection methods and you can run IFTTT recipes with it - sometimes.
Looks like there are a few competitors out there. As they compete, and people start to adopt this kind of technology, it should get better, and cheaper.
That might be interesting. If they work the bugs out and get a consistent product I would def get one. I drive my mini for fun and get decent gas mileage around town I'm a racer on the freeway I'm a grandma.... So that's not top priority.
I have had one for about 6 months now. I wouldn't call it useful, but it is interesting. It arbitrarily decides that over 70 is a negative and deducts points for every minute over. And hard brakes and accelerations are also squawked at, which in a MINI is all the time. I now use it mostly to condition my 15 YO to expect it in his car next year.
The latest update to the app made it usable again. There are some cool features. If you got reimbursed for mileage on a regular basis, this would be quite handy.
