The TraceTogether App is a state-of-the-art digital tracing application for contract tracing purposes that employs Bluetooth technology to determine your distance from other TraceTogether devices in the vicinity. Travellers need not be alarmed that GPS location data, mobile network, and other Wi-Fi data is being collected by the app as it is not used for third party data collection. Everyone who is touching down in Singapore must download the app before leaving their home country and activate it by registering a mobile number and creating a profile. The TraceTogether download and activation are not necessary for children under 12, those with special needs, or disability.
