United Nations Technology Innovation Labs (UNTIL) iPhone and Android app uses bluetooth to measure the distance to other phones and devices.
It alerts people when they get too close to another person to 'educate people about social distancing' to slow the spread of coronavirus - but seems to pick up any bluetooth device not just phones.
This includes devices like smart speakers, televisions and even sensors that make use of the short range wireless technology - so it is generating false positives.
A number of countries are using bluetooth based apps to help in tracking the virus - in this case it is just used to alert a user if they're breaking social distancing guidelines
The UNTIL app is designed to alert users when another Bluetooth device comes within 1.5 metres (hence the name 1point5) - that's about 5ft.
