Google realizes that you don’t always want to buy or rent a movie or TV show, so today it’s updating the Play Movies & TV app for Android with a helpful feature that will show which apps are currently streaming whatever it is you’re trying to watch.

This works for many of the popular go-tos like Amazon Prime Video, Hulu, HBO Go / Now, Showtime, and a slew of cable-authenticated apps like ABC, CBS, NBC, Fox, HGTV, Comedy Central, and others.
