Zoom has cancelled all work on new features and will instead focus on its security and privacy. The company's founder and chief executive Eric Yuan apologised to users after a run of problems with the app and outlined a plan to improve it over the next 90 days. He admitted that the app has struggled with the vast number of new users that have come to it in recent weeks. As well as a rapid increase in the use of the platform, the extra scrutiny has brought attention to a host of security and privacy bugs within the app. Mr Yuan confirmed that for the next 90 days, all new feature development was being frozen to instead focus engineering resources on security issues.

Facebook Messenger has finally launched a Mac and Windows app to allow people to chat on their computer. Just like the version for iOS and Android, the updated app supports group video chats, allowing numerous people to speak at once. As with other video chat platforms, Facebook said it has seen a drastic rise in the number of people using its platforms in recent weeks, as they keep up with each other through lockdowns. Over the last month, there was more than a 100 per cent increase in the number of people using their desktop browser for audio and video calls, it said. As with other versions of Messenger and Facebook more generally, the desktop app and its video call features are unlimited and free, though the company is able to collect information about people as they use it.

Google's Art & Culture app will now let you turn any of your pictures into a masterpiece. The new feature, called "Art Transfer", takes your photo and uses artificial intelligence to give it the style of a famous artwork. Users can choose "dozens" of well-known paintings and borrow their style for any image. The feature can be used by opening up the tool – which exists as a separate tool for iOS and Android – and then selecting the Camera menu at the bottom. On there should be the option for Art Transfer, which will open up the feature.

Sky internet has been hit by network problems, leaving people unable to load websites. The company said that it was working to fix the problems, which came as many people are working from home as part of the UK's lockdown. Issues appeared to be particularly prevalent in Cornwall, which Sky said had been traced to a technical problem. "After investigation by the support teams we are now able to confirm that there is a multiple exchange outage in the area," it wrote on Twitter. "We are working hard to put a fix in place."

Dyson has released a fan that both cleans and wets the air as well as cooling users down. The fan is intended both to humidify the air and purify it, with the aim of improving the conditions inside people's houses. The new fan – known as the Dyson Pure Humidify Cool – costs £599.99. It is made up of a large unit with a tank at the bottom for water, which is expelled using the bladeless fan at the top. While the company made a humidifier before, under the name AM10, it did not have the ability to purify the air that it expelled.

Apple has made millions of face masks by calling on the supply chain it usually works with to build its iPhones, Macs and other products. The company has brought together an effort that includes its "product designers, engineering, operations, packaging teams, and our suppliers" to help make the face shields for health workers, according to chief executive Tim Cook. Apple is just one of the many technology companies that has looked to help fight the spread of coronavirus, with companies across Silicon Valley offering products and help for health workers and the fight against covid-19 more generally. The new work has seen it create 20 million of the masks and it has started to distribute them among healthcare workers already, Mr Cook said. "Our first shipment was delivered to Kaiser hospital facilities in the Santa Clara Valley this past week, and the feedback from doctors was very positive," he said.

Quibi, a new streaming service featuring many of the world's biggest celebrities, has finally launched – and prompted confusion among those who are the first to use it. The company has launched in the hope of being a version of streaming services like Netflix but with a focus on mobile phones. The hype before it launched has included ads during the Super Bowl and shows starring celebrities from Reece Witherspoon to Liam Hemsworth. The launch came with 175 new shows, ranging from scripted drama to real-life celebrity stories, all of which are short and made to be watched with the phone pointed up vertically rather than the usual landscape view. It has raised $1.75 billion to fund the shows and the app itself on the strength of that idea.

A smart toilet capable of detecting early warning signs of cancer and other serious diseases has been developed by scientists in the US. Researchers at Stanford University built the device using an upward-facing camera, test strips and artificial intelligence to analyse faeces and urine as they pass through. The disease-detecting technology could negate traditional stool tests and prove particularly useful for people who are genetically predisposed to certain conditions. It involves retro-fitting an ordinary toilet with all the necessary gadgets to perform the tests, together with a companion app that analyses the data and displays the results. The researchers who developed it hope it will one day be part of the average home bathroom.

WhatsApp has introduced major new changes that are intended to stop people spreading messages so easily. The update is intended to stop the spread of false stories, bad advice and misinformation about the coronavirus outbreak as well as more generally. The feature might initially appear strange for a social network, which usually encourage easy ways of forwarding on messages and increase the reach of more popular posts. But WhatsApp has said the feature is specifically intended to "constrain virality", to keep the app "personal and private" as well as looking to slow the spread of hoaxes and rumours. What do the new rules mean?

Facebook is launching a survey of its users that will attempt to track the spread of covid-19. The system will appear at the top of the news feed and encourage people to describe their own health so that information can be passed onto researchers. That data could then help guide responses to the crisis, including allowing the development of a heatmap of reported symptoms that can be used to track where coronavirus could be spreading. It is part of a series of responses to the outbreak revealed by Facebook as part of its "Data for Good" programme. As well as asking users to participate in the survey, Facebook will also use its data to help generate maps and charts of how people are behaving under coronavirus lockdown.
