Apple and Google launched software Wednesday that will allow public health authorities around the world to create mobile applications that notify people when they may have come in contact with someone who’s been diagnosed with the coronavirus.
The effort, which the two tech giants call an “exposure notification” tool and utilizes bluetooth radios within smartphones, will be part of a new software update the companies will be pushing out Wednesday. State and federal governments can use it to create contact tracing apps that citizens can download via Apple’s App Store or the Google Play store. People who have updated their phones with the latest software will be able to share their bluetooth signal, logging when the radio recognizes other people who have downloaded an app that uses the software.
Apple and Google said some US states and 22 countries would be using the software, but the companies declined to provide a list of all the government agencies using it.
Apple and Google provided endorsements of the software from officials in three US states, such as Doug Burgum, governor of North Dakota. “North Dakota is excited to be among the first states in the nation to utilize the exposure notification technology built by Apple and Google to help keep our citizens safe,” he wrote in a statement provided by the two companies.
The software has come under criticism recently because some public health authorities say it doesn’t provide the data necessary for them to improve their own contact tracing efforts, which is being conducted by armies of real people conducting interviews with covid-19 patients.
In that effort, some government agencies were working on their own apps, even before Google and Apple announced they were working on the software on April 10. But those apps didn’t work properly because of restrictions the companies place on smartphones and because the phones running Google and Apple software don’t communicate well enough with each other.
As an alternative, Apple and Google created their own software, which removed some of the barriers public health authorities had wanted to remove, but placed new restrictions, limiting how public health authorities could use the data. For instance, a coronavirus patient being interviewed by public health officials cannot provide a list of people they may have contacted via bluetooth.
