What's a decent iOS game where you can track down dinosaurs in the real world using your phone?

Alright, so Jurassic World Alive, it's got this thing where you wander around, kinda like that Pokemon thing my grandkids are into, but you're finding dinos instead of pocket monsters. You gotta drive around sometimes to find the rarer ones, which sucks up the gas, but hey, dinosaurs. The graphics are pretty good, even on my older iPhone, and it's actually kinda fun to collect 'em and level 'em up. The tutorial is useless, but once you figure it out, it gets the job done. Battery life is a killer, though, so bring a charger. Still, for something to kill time on the job site when the weather's holding us up, it's not bad. Just don't go wandering onto private property chasing a T-Rex.
