## What is EV Logger?

EV Logger gives electric vehicle owners the ability to record energy use information to track range and energy efficiency in much the same way that a gas car owner might track gas mileage.

The app is customizable so the owner can choose what information items to record and the entry order.

Given sufficient data, EV Logger provides some simple calculations like battery-to-wheel efficiency per drive and wall-to-wheel efficiency per drive/charge cycle. The recorded data may be exported for further analysis.

The current version contains appropriate settings for a Nissan LEAF, RAV4 EV, Tesla Roadster, Tesla Model S, Model X, Model 3 & Model Y and a generic setting that can be customized for other electric vehicles.

### 5/5 — Just what I was looking for

*2024-03-15*

The app is tailored for logging trips and charging sessions for EVs. There are plenty of fields from which you can pick and choose to record as much or as little information as desired. It works great for me, worth the small price. I only regret my Ioniq 5 does not have a specific listing, but it was easy to create my own vehicle profile.

### 3/5 — Can’t see settings in Dark Mode. No degrees C.

*2023-06-08*

Paid for this only to find that I can’t see what model car I’m choosing in the settings while I’m using dark mode. And we need Celsius in England, we don’t use Fahrenheit. Also, it’s a shame all the info I’m typing in is just a log, it would be lovely for the app to do something useful with the log data in the form of a graph or statistics at a glance.

### 1/5 — Great idea but unreliable

*2021-08-09*

I just purchased this app and after entering two trips it quit working.  The field names no longer were visible which doesn’t do me much good when I’m trying to enter data!

**Developer response:** Thanks for the feedback. The problem you experienced was probably related to a Dark Mode issue that is fixed in version 1.6. Please give that a try and let us know if you are still having an issue.

### 2/5 — No statistics

*2018-04-17*

This app is good for recording trip and charge information, but it doesn’t DO anything with that data.  There is no efficiency calculation or total energy usage for a given time period or total/average cost of charging, etc. 

 I would like something more like the “Road Trip” app for ICE vehicles.  Something that compiles historical data into interesting/useful statistics.  It would be nice to have statistics on how long it takes to charge using L1, L2 or DCFC charging stations.

### 5/5 — So helpful, but it needs more data fields

*2013-08-19*

I have been using this logging app for over 6 months now, and I find it invaluable to track the health of my battery and my car, but it's gotten to the point where this app REALLY needs some additional fields. There is a new app out there being developed by a Nissan Leaf owner which provides information from the CAR-CAN of the Nissan Leaf and I'd love to be able to log this extra data into my EV Logger app, but can't really do it efficiently (I'm using notes right now, and it's not the best it can be). 

The data we really need to be able to track and log are GIDs, Ahr, CAP%, and Health%. In addition to that, it would be so much more helpful if we could have at least one decimal point granularity on the all tempurature logging data and the SOC% data.

Other than those additional pieces of information and some extra precision on the temp and SOC fields, this is a fantastic app! Thanks for the hard work and thanks in advance for considering these changes. :)

**Developer response:** Battery capacity Ah, SOH and Hx are all available fields, just not included in the default configuration for the LEAF. To enable those fields, go to a charge or drive record, hit the customize button, scroll to the bottom of the "hidden items" group and drag the fields you want up into the "visible items". Any of those items can be added to any of the record types (drive, charge, park and reset).
