The red iPhone 7 and 7 Plus differ from other models in colour only.
Apple has launched a red version of its iPhone 7 and 7 Plus as well as a new video app for iOS.
The red iPhone celebrates Apple’s 10-year partnership with Red, an organisation that aims to combat Aids.
A video app for iOS, called Clips, has also been revealed and will be released with iOS 10.3, which is expected to launch soon.
Apple seem to increasingly be trying to associate its products with ethical ideals. All of the money raised by Red – a venture originally founded by U2 musician Bono and activist Bobby Shriver – goes to Global Fund HIV/Aids grants. Among other things, these grants provide testing and treatment for patients with the aim of wiping out transmission of HIV.
Some profits from sales of the phones will go towards Red.
Apple was increasingly branding itself as a force for “social good”, suggested tech analyst James Moar, at Juniper Research.
“It is a way of them kind of beefing up that side of their business,” he told the BBC.
Apple also unveiled a new video app with playful features, such as stickers and filters, not unlike those made popular by Snapchat.
“Fun effects including comic book filters, speech bubbles, shapes and full-screen animated posters help bring out the personality in videos made with Clips.”
Apple also announced a new iPad with a 9.7in (25 cm) screen and an improved processor. Models in the UK will start at £339 – one of the lowest priced so far – for a 32GB wi-fi only version.
