The new Apple Watch Series 6 is finally launched

Apple's popular smartwatch is getting an update, called the Apple Watch Series 6, with a key new health sensor, as well as features focused on making the gadget easier to use with kids. The new sensor can measure your blood oxygen level in 15 seconds and will also track your blood oxygen in the background. Apple also announced new services for the device that are focused on health and family. The company showed off a new service called Fitness Plus, which offers a variety of weekly workout routines for $9.99 a month. The company also said it will also have a feature called Family Setup, allowing parents to set up their children's watch to help track their kids' location and control who they talk to using iMessage. The feature requires a cellular version of the Apple Watch, but it doesn't require a child to have an iPhone. Apple unveiled the new watch series during the company's annual fall product announcement event.
