So even as more countries’ apps go live, social distancing will continue to be the main way for people to protect themselves for the time being. The UK guidance asks people to stay more than two metres away from those they encounter outside, and to avoid non-essential public transport journeys and other social gatherings.

Maintaining such restrictions will be a challenge as lockdowns are lifted, since social distancing goes against human instinct. One piece of research also found that an essential factor in people being willing to social distance was if they thought they could do it; the longer people are expected to stick to the coronavirus guidelines, the more they will probably feel they can’t keep doing it.

The research shows that people don’t necessarily social distance, despite their best intentions. In the words of Chris Whitty, the UK chief medical adviser, “enthusiasm at some point lags”. Contact tracing apps will help here, but there is a way of making them more effective that seems to have been overlooked.

These apps work by storing the Bluetooth identifier being transmitted from every phone they encounter. The received signal strength will also be stored to give a rough approximation of distance, though this varies between phones so isn’t hugely accurate.

On a regular basis, the app will fetch the identifiers of all people in the country who have tested positive for COVID-19 or are at very high risk of having been infected. It will then check back and see if its user has previously encountered any of these identifiers, and trigger a warning message or phone call that tells the user to get tested or take other steps. This will be people’s only guide to how well they are successfully social-distancing – apart from developing symptoms.

To make this better, we could add a feature that works in a similar way to how fitness tracking apps give feedback on a person’s daily performance to “nudge” them into doing a little better tomorrow. Apps could tell users how many people they are coming into contact with each day as a whole, and what kind of risk profile that gives them – comparing them with other users without giving any private information away. The data could also differentiate between long and short encounters. Users could then track their efforts at distancing in real time.
