The Top Grossing chart ranks apps by total revenue — combining paid downloads and in-app purchases — making it the best measure of which apps are actually making money. These rankings are sourced directly from the South Korea App Store and updated every day. 5 of these 50 apps are newcomers since the previous update; 일랑 – 요즘 직장인 소개팅 (채팅, 동네친구, 만남) made the biggest jump, climbing from #48 to #27; KakaoTalk : Messenger holds a steady position at #1, where it has charted for 113 days.
