One of my favorite YouTube channels (Teslanomics.co) recommended this App as a way to keep track of your traveling stats- best of all, it is (for the moment) Free.
TezLab is available through the iOS app store, and has been an interesting view of the past 22,000 miles on our X75D since December of 2017. Here’s the record of the 69 unique Superchargers we’ve used – which they credit with more than $1685.00 in fuel savings to date (I did not begin using the app until I had about a thousand miles on the ModelX).
On Phantom drain – I’m still working through that to see if I believe all of the data Tezlab is showing, but it’s interesting nonetheless.
Here are two more screenshot sets, which you can find at Tezlab in the iTunes store
