Kerry Wan/ZDNET Google just unveiled its new Pixel Watch 4, and upon first glance, it's pretty similar to the Galaxy Watch 8 Samsung released last month. They're both Android smartwatches with AI-powered health coaches, they have around the same battery life, brightness, and storage, and notably, they're the same price.

The feature is available on the Google Pixel Watch 4 LTE.

You want free health features While the Pixel Watch 4 offers improved sleep staging and temperature sensing algorithms for further accuracy, most of Google's new AI-powered health coach features are hidden behind Fitbit Premium, which costs $10 a month or $80 annually.

Samsung's new Running Coach feature tests your running ability with a 12-minute test, ranks it out of 10, and provides a tailored training program based on your ability and recovery. Samsung Health also suggests bedtimes based on your sleep needs -- just like Google.

To activate it, just press your thumb on the BioActive sensor, and the watch lets you know if your levels are within adequate or inadequate ranges. Galaxy Watch 8 (left) and Pixel Watch 3 (right). Nina Raemont/ZDNET 2. You want a thinner watch The Galaxy Watch 8 is a thinner device that's easy to wear. While I've only worn the Pixel Watch 4 for a few minutes during a device demo, I noted that it was quite a bit chunkier. Some people might appreciate this, but if you have smaller wrists, the Galaxy Watch 8 will likely be a better fit. Alternatives to consider
