The phrase refers to applications that offer access to streaming video content, typically television dramas and movies, without requiring payment and are not widely known or easily found through conventional app store searches. These applications often operate outside of established distribution channels, making them less visible to the general public.
The appeal of such applications lies in their ability to provide cost-free entertainment. However, their use may present certain risks. Historically, the availability of free content has often been associated with copyright infringement, potential security vulnerabilities, and the absence of official support or guarantees of service quality. Furthermore, the legality of accessing content through these means varies by jurisdiction.
