I'm sure it's the same app, problem is it doesn't show the price anymore after you've purchased it, but I've heard rumor that it's a lot more expensive. I paid $15, 3 yrs ago, and I remember thinking, I'll wait until it goes on sale for $5. It never went on sale. It's like FSD, always going up in price!
Yeah I bought it for $15 back then, and used it for a bit but then decided I didnt like the idea of any third party apps having access to my car (I know its a token), and also (and more importantly), that I was only looking into it because of stress about the battery. I also had some issues with the car staying asleep back then when trying both teslafi and stats.
I dont regret buying it, I got more than $15 of use out of it the little time I used it. The feature set has expanded since then as well, from what I read, I just dont use third party apps as I mentioned.
I only said the part about "im not endorsing it or anything", simply because of the fact that I was posting about it, and have a moderator tag here, and even though most of the time I am posting as myself, people will sometimes see things I say and ascribe more weight to them than I intend.
