It's hoped the information they gather can be used to alert people whether they pose a risk of spreading the contagion, and need to isolate.
At the start, the centralised approach was seen pioneering. Singapore's TraceTogether was widely viewed as the one to emulate. But that changed after it emerged the app was only being used by about 20% of the local population, and there had been a resurgence of Covid-19 cases. Part of the problem is that TraceTogether does not work properly when in the background on iPhones because of the way Apple restricts use of Bluetooth.
Australia, another early adopter of the centralised approach, launched its CovidSafe app based on TraceTogether, with Australia, Singapore, The United Kingdom and many other countries taking the smartphone app approach seriously should we be starting to protect our technology devices better than what we are if we are going to be spending more time on them?
Research shows cell phones carry 10 x more bacteria than most toilet seats so should we be looking at the probability of having all our devices covered with antibacterial screen protectors? If we are going to be checking a contact tracing app a few times a day, the screen protectors will significantly help reduce the spread of pathogens.
We have an extensive range of anti bacterial screen protectors at Screenshield and if you can't find the size you are after send us a message and we will custom cut one for you.
