ONE Store Becomes Korea's No. 2 App Marketplace

As of late December 2025, ONE Store has proudly announced its position as the second-largest app marketplace in South Korea, a significant achievement detailed in IGAWorks' Mobile Index report. The report highlights that ONE Store holds a 12.6% share of game transaction values from the second half of 2020 through the first half of 2025, solidifying its competitive stance in a market that faces robust competition from global players.

Founded in 2016, ONE Store has set itself apart from its competitors by prioritizing lower fees, marketing support, and user incentives designed to encourage both developer partnership and user engagement. This strategy has proven effective, as developers utilizing the platform have saved approximately KRW 380 billion (around US$257 million) in cumulative fees, while users enjoyed discounts amounting to KRW 690 billion (approximately US$467 million).

In the first half of 2025, ONE Store witnessed an impressive 49.2% share of transaction value in the top 50 highest-grossing games that were available in other major app marketplaces, emphasizing the growing preference among users for platforms that deliver better value. Moreover, the platform's Average Revenue Per Paying User (ARPPU) stood about five times higher than that of its competitors, indicating strong user loyalty and a higher spending capacity.

The genre-specific metrics further illustrate ONE Store’s dominance in the gaming sector. In the first half of 2025, it captured 50.9% in RPG, 64.8% in Simulation, and 49.2% in Strategy games among the highest-grossing titles. The average share across these three prominent categories in Korea reached an impressive 52.9%, demonstrating the marketplace's appeal to gamers.

In light of these results, it is evident that ONE Store's commitment to fostering a beneficial ecosystem for both developers and users has paid off. By continuing to innovate and enhance the user experience, ONE Store is positioning itself as a leader in the app marketplace landscape, making significant strides toward long-term success.

As ONE Store maintains its momentum, the app marketplace remains an exciting platform for developers and gamers alike, presenting new opportunities for engagement and revenue generation within the vibrant South Korean market. The ongoing improvements and solid performance statistics indicate that ONE Store is not only on a growth path but is also reshaping the way users and developers interact within the mobile app ecosystem. The future looks bright for ONE Store as it continues to capture the attention and trust of the digital community in South Korea and beyond.
