Currently, the application market is becoming saturated, with numerous apps in each segment.In such an environment, it is difficult for apps to enter the core position and achieve profitability.The challenge facing developers is not only to attract users, but also how to maintain user loyalty and achieve sustained profitability amid fierce competition.

According to statistics, the number of available apps in major app stores around the world (such as Google Play and Apple App Store) will exceed 8 million by 2024. This data fully demonstrates the high maturity of the app market, which also means that developers need to face a lot of competition. How to accurately identify market demand and find their own foothold has become an unavoidable challenge.
Although the total number of smart device users worldwide is increasing, the growth of app downloads has slowed down. The global app download growth rate in 2023 is only 4.3%, far lower than 12.1% in 2019. It has become more difficult to acquire new users, and developers need to innovate to attract existing stock users.
In the App Store, the top 200 apps account for nearly 90% of downloads, and apps ranked lower are unlikely to gain user attention. Users usually give priority to apps with well-known brands or high ratings, and exposure opportunities in the market are becoming increasingly limited for small and medium-sized developers.
Data shows that the total revenue of the application market will reach US$500 billion in 2023, of which 47% will come from subscription services, but mainly concentrated in a few top applications.
Due to fierce competition, the free model has become the mainstream strategy for developers to attract users, but this is often difficult to achieve profitability. Most users expect high-quality, low-priced or even free services, which further compresses profit margins.
Most small and medium-sized developers face difficulties in making profits and need to flexibly adjust their profit strategies and find new profit models to ensure sustainable sources of income and long-term development.
