An energy economy calculator for your Nissan LEAF.

Is the Nissan LEAF dash reading letting you down? We call it the Guess-O-Meter because it's all over the place! Wouldn't it be cool if you could more accurately determine your range and better predict energy usage for a trip? You can with this app!

Calculate how much energy your Nissan LEAF will use on a route given it's battery size, charge level, capacity bars level, route distance, battery temperature, speed, air temperature, elevation, and climate control usage.

See how efficient you must be given battery charge, temperature, a route distance, and battery degradation.

This app is based upon the Nissan LEAF Range Chart from Tony Williams.

Works well. Need 2018 version!

Worked well with my 2011. Using it now for general ideas but would love to have the 40kw charts added in.

Your R2 Unit for your LEAF

Everyone needs an helping hand to make sure you've got enough charge to get from point A to B and back home when you are at the edge of your range.

This little app takes care of you!

Great for route planning and peace of mind!
