In addition to exciting its loyal legion of fans, HBO’s “Game of Thrones” premiere was also once again great news for installs of the network’s app for cord cutters, HBO NOW, which shot to the top of the App Store this weekend. The app this weekend saw a combined 300,000-plus new mobile subscribers in the U.S. across both Apple’s App Store and Google Play, according to preliminary estimates from Sensor Tower.

This is the highest the app has ranked on the U.S. iPhone App Store in three years, Sensor Tower notes, with its previous highest ranking on April 24, 2016 for the Season 6 “Game of Thrones” premiere. At that time, the app had seen 160,000 downloads on just the one day.
