Is your phone rooted? Turo's specs from the store show 5.0+. Try zipcar app--it's also known to not work on rooted phones.
I forget what it's called, but there is definitely a rent-a-car-from-random-person app that exists. I just saw it a few days ago. In the review some people were saying everything was wonderful and some people were saying the car they got was a filthy piece of shit.

Turo, mentioned in the article, already does this and I have rented some truly amazing bucket list cars.
