Pretty cool app, the Only thing I thought would be useful in addition to all the units you get but, ads a map so you can check for alternate routes, and something to give you a ballpark of fuel prices nationwide.
To be able to get value out of it you need to know details of your car such as its fuel efficiency or the total distance of your trip. This app does not auto calculate distance from point a to b, or estimate gas mileage based on make and model of car.
Awesome to help plan your trips gas expenses if doing long distance traveling
I like it because it's a short and simple and very easy to use.
Simple... Efficient... Very less ads... Has all the tools to calculate fuel efficiency with all types of data...
ver 4.22 - This new version allows to calculate trip's parameters during driving (by GPS)
