About this app

Note: LeafSpy is designed for the 2011 thru 2017 Nissan Leaf. For the 2018 Leaf you will need LeafSpy Pro which supports all model years.

Before you purchase "Leaf Spy" or the more advanced "Leaf Spy Pro" please be sure to first install the Free version "Leaf Spy Lite" to confirm you have a phone (or android device) and ELM327 OBDII Bluetooth adapter that works with your Leaf.

Once you have the Lite version running and telling you about your battery you can then purchase either the full version "Leaf Spy" or the more advanced version "Leaf Spy Pro".

The Leaf Spy application allows anyone with a Nissan Leaf electric vehicle, Android device with Bluetooth and an ELM327 OBDII Bluetooth adapter the ability to monitor their battery and other vehicle information normally visible only to the dealer.

Due to a recent cost reduction (and feature reduction) many of the cheap ELM327 OBDII Bluetooth adapters from Asia no longer work with the Leaf and report themselves to be version 2.1. The only one currently recommended is the Bluetooth Konnwei KW902 which still supports all the needed ELM commands to communicate with the Leaf.

Not a great app. All the information is there, and no doubt it is some achievement to extract it. But the interface is absoutely horrible, like something out of Windows 3.1. Nothing is intuitive. Driving with it on is a pain because it switches between night and day mode seemingly randomly. All of the useful information is obfusticated with lots of other information. All this might be forgivable if the app cost a few quid but for the price charged the UI should be a lot better.

Could not use despite checking my adapter worked in Leafspy Lite first - it seems there is no option for Bluetooth 4 LE even though it is included in Lite version. Have requested refund and will repurchase if this is resolved.

Had to refund. The Lite version works fine so I wanted to upgrade. But the pro version only works if you can pair with your OBD reader, and I can't.
