About Our App

GoCoronaGo (GCG) is a digital contact tracing app for COVID-19. It uses Bluetooth Low Energy (BLE) to advertise and collect a random device ID of other nearby GCG users. These anonymized "contact" IDs are sent to a backend server and stitched to form a temporal contact network. Analytics over this network helps evaluate various risk scores for a user. It also helps quickly identify primary, secondary and tertiary contacts with users who are later diagnosed as COVID positive.

A Wider Contact Network

Unlike other contact tracing apps which can alert only primary contacts, GCG is designed to trace secondary and tertiary contacts with COVID+ individuals and notify you. This is made possible by using a central server to stitch individual contacts together.


Choose what you share! The app uses Bluetooth technology to detect and share randomly generated unique IDs. These IDs do not contain any personal information. Users can additionally choose to share mobile numbers and GPS location information for extra features.

Proximity and Risk Scores

Two's company three's a crowd! GCG analytics gives you feedback on your extent of social distancing. We also share risk scores when there is a possible contact path between you and a COVID+ individual. Of course all of this uses anonymized data. We only communicate using your unique IDs but don't know who you are.

News Alerts and Stats

Stay informed. We keep you updated on the latest research on COVID-19, debunk COVID myths, provide India and State COVID statistics, and remind you to follow safe practices with our notifications. Our alerts will also help you play your part in social distancing and contact tracing.

Designed and Built at IISc

Contribute to our understanding of epidemics. Data collected from the app will be used to build predictive temporal network models for research on disease spreading. These decision-support tools will be crucial to help cities get back on track. For more technical details on GoCoronaGo, see our article in the Journal of the Indian Institute of Science.

Institutions Welcome!

GCG is for institutions, not just individuals. We are deploying our app in dense work environments in Bangalore which have a high risk of spreading the virus after the lockdown ends. Get in touch with us today to know more.
