According to market research firm Sensor Tower on the 24th, Gemini's cumulative iOS (Apple App Store) revenue worldwide was recorded at approximately $21 million. Of this, South Korea accounted for 11.4%, recording the second-largest share after the United States (23.7%).

Currently, ChatGPT still ranks first in terms of daily active users in the domestic generative AI app market, but the gap has been gradually narrowing since the launch of Gemini 3. From January 1 last year to January 15 this year, the difference in average daily active users between the two services was over 7 times, but after the launch of Gemini 3, it narrowed to about 4 times.
Additionally, before the launch of Gemini 3, only 23.2% of ChatGPT users also used Gemini, but after the launch, it increased significantly to 40.8%. Conversely, among Gemini users, the proportion using ChatGPT showed a gradual increase from 57.5% to 63%.
