Apple unveils new iPhone 14, Ultra Watch

Apple has introduced a range of new iPhone 14 models capable of sending a call for help via satellite during an emergency and crash-detection ability.

The iPhone 14 Plus model will have a larger screen like Apple's iPhone Pro models but the same A15 processor chip as the previous iPhone 13.

The Cupertino, California-based company also showed a trio of new Apple Watches during its "Far Out" showcase event. 

These including a new Watch Ultra model aimed at extreme sports and diving.

The Ultra has a bigger battery to last through events like triathlons and better waterproofing and temperature resistance to operate in outdoor environments, as well as better GPS tracking for sports.

The new Watches include an upgraded budget model called the SE and a Series 8 Watch with crash detection and low-power mode for 36 hours of battery life.

The Series 8 with cellular will start at $499 and the SE will start at $299 with cellular.

The Ultra, which includes cellular in its base model, will start at $799.

Apple said the new Series 8 watch has a temperature sensor that will work in conjunction with its previously released cycle tracking app to retroactively detect when a person has begun ovulating.

The company emphasized the privacy approach of its cycle tracking. Privacy and reproductive health data has become a focus for tech companies in the wake of a US Supreme Court decision that ended a constitutional right to abortion in the United States.

Apple said it does not have the key to decrypt health data such as cycle tracking.

But while accessories like the Apple Watch have driven incremental sales from Apple's existing user base, the iPhone remains the bedrock of its business with 52.4 per cent of sales in its most recent fiscal year.
