Frequently asked questions

watchOS 27 adds a Siri app with conversation history, one Find My app in place of three, and a Readiness app for the Series 12 and Ultra 4.
Some Series 12 and Ultra 4 owners report burning and redness under the sensor, and nobody has confirmed a cause. Apple advises a clean, well-fitted band and a physician visit if irritation appears.
DC Rainmaker's Ray Maker found Apple's new Readiness Score tracks hard days and sick days well, but it sometimes shows no value. Battery was weak in week one, then settled at a day to a day and a half.
AppleInsider calls the $399 Series 12 the best non-Ultra Apple Watch yet, thanks to a new health sensor and tougher glass. Its reviewer tells Series 11 owners to wait for Audio Intelligence.
The patent expired in 2022, so current Apple Watch heart-rate features are untouched, but the total Apple owes Masimo is now around $818 million.
It is accurate enough to train by on runs and rides, but one tester says it is no better than recent Garmins, and a chest strap is still the pick for HIIT.
A federal judge refused to dismiss Apple's suit saying a former Apple Watch engineer took trade secrets to Oppo. Oppo has until October 21 to file its defenses.
Gizmodo's review of the Apple Watch Ultra 4 finds better heart-rate accuracy and no price increase, but key Apple Intelligence health features aren't live yet.

It's for people switching from an iPhone who want to keep their watch. You still can't set up an Apple Watch on Android from the box.
The reboots new Series 12 and Ultra 4 owners have been hitting should stop once this is installed. Apple still hasn't said what was causing them.
It's switched off and Apple hasn't announced it, so watch screenshots still work the old way for now. If it ships, you'll be able to delete a stray capture before it lands in your iPhone's photo library.
Lifehacker's health editor used to rate Apple's sensor a C. She now puts it in the same tier as the Forerunner 570, with one catch: it skips readings it isn't sure of.
Apple hasn't decided to ship it, and Bloomberg's reporting puts any release in 2028 at the earliest, so the Apple Watch stays Apple's only fitness wearable for years yet.
Apple removed the quick way to jump between recent apps in watchOS 27 and is now testing its return, though on a new long press rather than the old Digital Crown double-click. It is a beta, so the gesture could still change.
About 30 owners report Neural Engine crashes that restart the watch, even after a reset. Apple hasn't commented.
The feature still runs on the Series 11 and Ultra 3, and Apple has not explained why its newest watches are off the list.
