The phrase refers to applications designed for Apple’s mobile operating system that facilitate the downloading of online videos for offline access. These tools were intended to allow users to save video content from various online platforms directly onto their iPhones or iPads.
Such applications gained popularity due to the ability to watch videos without requiring a constant internet connection, thereby conserving data usage and allowing for viewing in areas with limited or no connectivity. The availability and functionality of these applications have evolved over time, often facing scrutiny and restrictions from app store policies due to copyright concerns and terms of service agreements of various video-hosting platforms.
