There is something referred to as a GIDometer by people on the mynissianleaf forum. I don’t think it is an android app though. > > Have you ever wondered WHY the Leaf's instrumentation is so crappy?

Their marketing people told them range anxiety was a big issue, so they thought they needed to come up with a single number that indicated how much further the car could go. It is impossible to know that. Given that the capacity is so low (compared to the capacity of a typical tank of gasoline) there isn’t much room for error. On my old ICE vehicle, the fuel gauge would read empty and the warning light would start to flicker when there was about 3 gallons left in the 15 gallon tank. The warning light would come on solid somewhere around 2.5 to 1.5 gallons left. The Leaf battery pack with a full charge is about the equivalent of a Nissan Versa (essentially the same vehicle with an ICE) with about a 2.5 gallon tank. The Versa’s fuel gauge would probably read empty when it had the equivalent range of a fully charged Leaf. The best range gauge I ever saw was in my Honda EVPlus. It consisted of a horizontal bar chart with 0 on the left and 120 miles on the right. The bar would display in yellow how far the car could go the way it was being driven right now. Press on the accelerator hard, the bar would move to the left towards zero. Ease off it would move to the right towards 120. Go up hill, the bar would move to the left, Go down hill, it would move to the right. There was a green extension to the yellow bar indicating how far the car could go when driven in its most efficient manner. It was an interesting game attempting to drive so the yellow bar covered as much of the green bar as possible. The Honda EVPlus had much better range than the Nissan Leaf. When I was forced to give it back after six years and 60,000 miles, I could still drive more than 100 miles on a charge. The best I have ever been able to do with my Leaf was 81 miles. The Leaf is a much bigger car and nicer in many respects.
