The new software comes with “a million ways to customize your lock screen,” Joanna writes, as well as numerous other updates to make your iPhone feel fresh. You can set up medication reminders, as detailed by Family & Tech columnist Julie Jargon, or even unsend an iMessage.

The best part? Apple’s software updates are free.

Apple’s newest regular smartwatches, the Series 8 and SE, look like their predecessors. But they pack hardware improvements under the hood that “can possibly save your life,” Personal Tech columnist Nicole Nguyen writes. And the more premium model, the Apple Watch Series 8, includes temperature tracking that could help you conceive a baby.

The most noticeable improvements for most users, though, come with the newest Apple Watch software, Nicole says. WatchOS 9—which adds a medication reminder, sleep-stage information and more—is also available for recent Apple Watch models going back to the Series 4.

If regular fitness tracking isn’t enough for you, Apple has another option: the Apple Watch Ultra. The more rugged—and heftier—smartwatch was designed with extreme athletes in mind.

Nicole put it to the test during a two-day hike in the mountains. She found that it delivers on Apple’s multiday battery-life claims, but “leaves something to be desired for those accustomed to premium athlete-focused GPS watches.”

Does Apple’s Crash Detection Work? We Totaled Some Cars to Find Out.
 

With this year’s new iPhones and Apple Watches, Apple made an unusual pitch: Buy these devices to stay safe. It included car-crash detection in all new models and a soon-to-arrive satellite-powered SOS connection in the new phones, to get you emergency help when you’re out of cellular range.

Joanna didn’t just take Apple’s word that it works: She tested the new crash-detection feature at a junkyard with a demolition-derby champ and a few cars that were headed to the scrapper. The results were well worth the effort.

You wouldn’t be alone in thinking the new AirPods Pro are no different from the old AirPods Pro. After all, they both have the white bud-and-stem design. But the differences are apparent as soon as you put the new AirPods in your ears, writes Nicole.

“They do sound better than the originals—and they block sounds better, too,” she says. If you lose your AirPods (a pretty common occurrence for many earbud owners), they’re also easier to locate.
