In its lawsuit, the Department of Justice uses the Apple Watch as a piece of evidence to justify its claim that Apple is a monopoly.
Apple’s smartwatch—Apple Watch—is only compatible with the iPhone. So, if Apple can steer a user towards buying an Apple Watch, it becomes more costly for that user to purchase a different kind of smartphone because doing so requires the user to abandon their costly Apple Watch and purchase a new, Android-compatible smartwatch.
In response to the DOJ’s assertion, Apple confirmed for the first time that it at one point considered Android support for the Apple Watch. After a three-year investigation, Apple says that it determined an Apple Watch with Android support wasn’t doable because of technical limitations. As such, it scrapped the idea.
This aligns with previous reporting from Bloomberg’s Mark Gurman. In a 2023 report, Gurman detailed Apple’s plans – including some of the “business considerations” – on bringing Apple Watch support to Android.
