First of all, the mobile APP initializes the APP through the splash screen page, and some apps load the page slowly, so they cover it up with advertising pages to avoid using empty pages, which will cause the user's visual emptiness.

Secondly, some apps don't take that long to initialize, but app developers use advertising pages to occupy the stay time in order to increase user stickiness and stay time.

Thirdly, APP advertising has gradually become a trend and inertia in the industry, and it is also a form of advertising revenue for many apps. Many well-known apps take the lead, while niche apps mainly make money by advertising, so these three-second advertisements are short but the advertising fees are also considerable.

For advertisements initiated by apps, many apps can be skipped manually. Some applications are at the top left, while others have the instruction "Skip the advertisement for 3 seconds" at the bottom right. Just poke it. But you have to poke your hand every time you open the app. Is there any way to completely block advertisements?
