This app is interesting and somewhat helpful, but a few simple changes would make it 5 star. For example, the manual provides no way to interpret the scores. On the 100 point scale, is 50 average, or is it like the letter grade scale? Who knows. I would also like to enter my usual mileage rates so the fuel savings indicator would be more accurate, maybe even store mileage for 2 cars. As a bonus, an auditory cue indicating windows should be rolled up for better mileage would be nice.

I got this app a few days ago and it's great. It has helped me learn to drive in a more environmentally friendly way and save gas and money. I figure just learning to drive smarter for 20 miles and I've easily paid for the app. I'm now trying to accelerate and decelerate more slowly and anticipate traffic ahead so I can avoid the constant stopping and starting. It's not possible to do this all the time, like heavy traffic, but going to the store and on longer trips it's sure to help me save gas. For a 1.0 version it's very good. I'd like to see more descriptions of the readouts and perhaps the ability to do comparisons with two different drivers. Definately worth the download.

I updated to the new version. The report card has a grade score this is easier to understand.

An easy and inexpensive way to decrease my fuel consumption and save money. I'm not ready to give up my SUV, so this is a great offset. I was ready to go with minimal time learning how to use the app.
