In the fiercely competitive app market, the time for app revenue is precisely calculated to every minute and every second. Developers rack their brains to improve retention and use advertising and other methods to bring in monetization. However, most people overlook a potential revenue opportunity – app idle time.

The time when users pause operations, run in the background, or even wait for loading actually hides huge monetization potential and is a potential revenue resource that has been ignored. By making reasonable use of this idle time, developers can reap unexpected passive income and open up a new revenue channel for the app. CastarSDK is a monetization solution created for this purpose.

What is CastarSDK

CastarSDK is a monetization tool without ads or interruptions. It takes lightweight design as its core concept and does not interfere with the normal operation of the application. The integration operation is simple and risk-free, and developers can pause or terminate it at any time. After integration, the SDK will run quietly in the background, bringing continuous income to developers by intelligently utilizing the idle public network resources of user devices. During this process, CastarSDK will not collect any user privacy data, nor will it interfere with the application interface. It will run silently throughout the process and quietly create actual income for you.

The Value of Idle Time

The idle time of applications is more than you think, which is a huge asset that has not been tapped. For example, when users pause while watching a video, use a tool app in the background, or even wait for loading or queueing for a match in a game, these periods are not active behaviors in the traditional sense, but the device is still online and is a potential resource that can generate revenue. CastarSDK uses this seemingly worthless time to bring developers considerable passive income.

Advantages of CastarSDK

Compared with traditional monetization solutions, the advantages of CastarSDK are “invisibility” and “stability”. It will not cause any interference to the original design and functions of the application, nor will it make users feel uncomfortable. At the same time, it does not rely on traditional indicators and will not be disturbed by external factors such as changes in advertising market prices, which makes its source of income more stable. More importantly, CastarSDK fully complies with GDPR and CCPA, protects privacy data, and is safer than traditional monetization methods.

Such a silent monetization method not only maintains a good user experience, but also brings additional stable income to developers.

Let Every Second Create Value

A successful application should fully exploit its potential and create value for you every second the application is running. Integrate CastarSDK to allow your application to develop new monetization capabilities, bringing you stable, long-term, and passive income that does not affect product quality!

Let the idle time of the application truly become your profit time!
