Trace Together

Singapore government launches new app for contact tracing to combat spread of COVID-19

TraceTogether works by exchanging short-distance Bluetooth signals between phones to detect other participating TraceTogether users in close proximity.

Currently, contact tracing relies on the recall and memory of interviewees. There were however, instances when interviewees could not remember all their contacts, or did not have information on whom they had been in contact with.

TraceTogether works by exchanging short-distance Bluetooth signals between phones to detect other participating TraceTogether users in close proximity. Records of such encounters are stored locally on each user’s phone. If a user is interviewed by MOH as part of the contact tracing efforts, he/she can consent to send his/her TraceTogether data to MOH.

This facilitates the contact tracing process, and enables contact tracers to inform TraceTogether users who are close contacts of COVID-19 cases more quickly. This enables users to take the necessary action sooner, such as monitoring his own health closely for signs of flu-like symptoms.

The TraceTogether app can be downloaded from the Android Google Play or Apple App Store.
