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.

A helpful App

Say goodbye to the GOM! This app uses realistic data in order to predict available travel distance in you Nissan Leaf.

Thanks for thinking this through. I have found it to be very accurate for my Leaf!

Can’t Use App W/40 KW Battery

Dated app, can only be used with 2017 or older Leaf.

Good App for accurate energy usage

I like it includes the elevation of start and end point to calculate. EV energy usage differ largely depending uphill or downhill. I wish it had drop-pin function to set route adding to text address input of start and end. Also, I wish I can save multiple routes. It's great App. Please keep up to make this app better.
