Very easy to setup, just a case of linking car to the app and then just charging and driving normally, so didn’t have to, unless I wanted to, change my driving pattern/routine. The app then works in t... See more

Battery degradation
Battery degradation is probably my number one concern when looking at a used EV. Having access to an independent reporting service to quantify whether a specific car is within an expected range of "normal" battery wear is hugely important to me. The app & the collection process is clear and user friendly, and the final report is of high quality and professional looking with more data points than I was expecting! 100% will be using them when buying and selling my next EV!

Extremely Useful App for Finding Out EV Health
A great App if you are thinking about getting, or have an EV.
The App provides information concerning the battery health of a specific car using data directly obtained from the actual car itself and comparing to other vehicles of the same type.
After completion of a number of journeys you can produce a comprehensive (but easy to understand) Health Report for the vehicle which gives you a classification for the Health of the Battery, Range Insights (for both the Seasons and Road Type), Predicted Range Performance, The battery age and remaining warranty and the number of previous keepers.
Not only would this information be of assistance when you are selling the car, it should be essential information to anyone thinking about buying an EV.

Ingenious!
A lovely app which is fun and easy to use and should be very useful when the time comes to sell our car. Just wish I’d thought to clean my wheels when I took the photo of them! ( The photo appears in the report)

Simple to use and peace of mind
We found it simple to install and use, it’s an easy way to learn about second hand EVs when considering purchasing. It was good for peace of mind before parting with our money, and we learned other things we couldn’t easily get from the online listings like where the charging port is.

Excellent EV health checker
Excellent EV health checker - used it when I bought my Tesla Model 3 and gave me assurances that the battery and car were of a high standard. Would recommend.
