Just after the release of iOS 12 in 2018, Apple introduced its own built-in screen time tracking tools and controls. It then began cracking down on third-party apps that had implemented their own screen time systems, saying they had done so through technologies that risked user privacy. What wasn’t available at the time? A Screen Time API that would have allowed developers to tap into Apple’s own Screen Time system and build their own experiences that augmented its capabilities. That’s now changed.
