Since I wrote the text below, these 2 hours have become 4+ (by my experience). Document that limit up front, and I will go to 5 stars!

Old review:
The free version is not fit for purpose -- parking slots become "pay or else" after 2 hours -- not enough for movie parking.
5 (say) hours, or last known spot, would be better; or make it an honest $2 (or $20, or ...)
The (free) swift finder app is better on this count, and not obviously worse on any other.
