SCAM, AVOID ⚠⚠⚠
Listed on AppAdvice as free today, but it's not, it's a scam. You still have to buy the Pro upgrade. So, really I would assume FindMyCar is always free initially and the developer just gets it listed with AppAdvice to draw in customers. If you look at past reviews from at least a year ago it looks like this isn't the first time this developer has pulled this stunt.
Again, I'm not convinced FindMyCar ever cost an initial price and the developer just uses AppAdvice to lure customers in, which is totally unethical in my book. I would not recommend FindMyCar at all. Using the AppAdvice service this way is completely shady and crooked.
And I would advise others not to upgrade to the Pro version. Because, after reading through many reviews for FindMyCar it looks as though even if you do pay for the Pro version, that it won't be activated and your money will be stolen essentially and you'll get nothing in return. It appears to me that FindMyCar is just ONE HUGE SCAM. AVOID ⚠⚠⚠ FindMyCar and developer big time!
