Happy LEAF aims to be the missing interface from the original Nissan LEAF. With Happy LEAF you can ease range anxiety by knowing how much energy is remaining in your battery, and see useful statistics from the car.
Happy LEAF allows you to modify the grid layout, and fully customize the Happy Leaf dashboard using widgets. Happy Leaf Pro also allows viewing previous trips and play them back like a movie.
The current iteration of this app is very slow, and needs refinement. The project is open source here if you would like to tinker with the code and help improve the experience: https://github.com/blandman/happyleaf
If you purchased Happy LEAF (Unreleased) prior to September 2017, please contact Brandon Martin.
