On my previous ICE car, I used a phone app called simply auto, so each time I filled up I would enter the mileage, gallons of gas, and cost. Is there a way I can find out the equivalent info on a Tesla? An app already designed for this?
I use teslafi.com. I don't really use it for tracking expenses, but it's a thing that it does. If you want a 4 week trial rather than a 2 week trial, you can use my username as a referral code.
