Another option you might want to explore is easy taxi, which is a more useful app in Chile in my experience. Most Chileans do not speak English (at all), and many taxi drivers are quite bold in trying to rip off foreigners, so be careful (though the risk of this is less on an app, as you can see exactly where you are on the map). Taxi drivers are by far the worst in this regard, other people are far more honest.
For convenience and due to the language barrier, simply getting a taxi at one of the counters in the airport is advised. They are professional, clean, and convenient, if not a bit expensive. There are also buses that are very, very cheap and just fine for about 1.600 CLP last time I took one (6 months ago).
