One of the most useful tools we have in limiting the spread of the virus is contact tracing. If we can quickly inform those who are at risk of unknowingly contracting the virus, those individuals can take precautions to prevent passing it on to others. Speed is an advantage.

What it does

We've built a digital contact tracing app. Existing methods of contact tracing range from making notes, calling people, to Governments forcibly publishing private GPS data.

This app aims to be in the middle, location tracking data must be volunteered. The data is always kept private and only used for the purpose of informing others who could be at risk. It is digital, so contact tracing is instant.

A few key drivers of the app

  • Keeping data anonymous, and submitting data voluntary
  • Keeping data as private as can be and only using it for the specific purpose of the app
  • Keeping it easy to use
  • Keeping it simple, solving a specific problem

How we built it

The backend was built with Node, it's hosted on AWS lambda. To power the database Mongo DB is used. That's because Mongo DB comes with geospatial queries out the box.

What's next for Trace Together

We want a fully fledged solution that governments and health authorities can use and be up and running within a matter of hours.
