Mobile Apps

India developed The AarogyaSetu app & introduced it on both Android and iOS, aimed at primarily tracking the community transmission and tracing the contact and travel history of individuals that are quarantined, infected or suspected of being susceptible to the SARS-CoV-2 coronavirus.
The app uses both the location data and Bluetooth-based proximity tracking on users' phones, in order to keep a track of individuals that may have either been carriers of the COVID-19 disease or been affected by it.

Similar practice was carried out by the UK when the pandemic started to spread. A startup launched an app, C-19 Covid Symptom Tracker, for people to self-report their symptoms. It was downloaded 7.5 lakh times in three days, & it helped to identify high-risk areas, among other things.

South Korea has an app called Corona 100m that has mapped the locations of Covid-19 patients and alerts users if they come within 100 metres of an infected person.

In China, apps developed by Alibaba and Tencent give people a color code based on their health condition and travel history. This code, decided by a big data-driven algorithm, will determine whether a person gains entry into a mall or a subway station, or can travel between cities.
