Apple reveals iPhone 14 Pro and Watch Ultra

Apple has unveiled the iPhone 14, with emergency satellite connectivity and car crash detection technology, at a launch event in the US.

The company revealed four versions of the new handset at its Cupertino headquarters, with an audience attending in person for the first time since the pandemic.

It also showed off a new extreme sports wearable - the Watch Ultra.

The event focused on next generation iPhone, Watch and AirPod products.

Apple CEO Tim Cook was on stage at the Steve Jobs theatre inside the tech giant's California campus - but the presentation itself was entirely pre-recorded.

Apple Watch Series 8
Apple Watch Series 8 has a number of new features, including car crash detection, temperature sensors for tracking ovulation cycles and a new low-power mode option.

People have been cautious about menstrual trackers since changes were made to abortion legislation in the US and there are concerns that data about periods could be used by law enforcement. Apple says the data on its devices will be encrypted and only accessible via a passcode or biometrics.

"We are taking our commitment to women's health even further," said Jeff Williams, chief operating officer at Apple.

Apple said a new automatic retrospective ovulation notification could help those who are trying to conceive.

If activated, the new watch can monitor body temperate every five seconds overnight, and detect tiny changes which can signal ovulation.

Another new feature is car crash detection. Using sensors, the watch will be able to identify a severe crash and will automatically connect its wearer with emergency services, provide their exact location and notify emergency contacts.

The Series 8 now also features a low power mode, a feature borrowed from the iPhone, that promises up to 36 hours of battery life on a full charge.

The Apple Watch Series 8 is priced from $399 in the US, ?419 in the UK.
