In the challenging present times, many social-distancing aids have been created in order to enforce / assist in social distancing. Most of them are based on Bluetooth or Wi-Fi. However they have their own inherent problems due to the nature of the Most current social-distancing aids are:

• Inaccurate: Most social-distancing apps use Bluetooth which is unreliable in detecting exact distances due to its wide range (around 10m).
• Not cross-platform: They do not usually work on both iOS and Android.
• Lack of privacy: They pose a risk to users’ privacy as they collect sensitive data.
• Passive: They do not prevent, rather aim to mitigate.

Our app sends and listens for near-ultrasonic sound to reliably detect any phone in a 2-3m radius to alert the user. It uses the attenuation of the signal strength along with other mechanisms to detect people only in close proximity. Each device acts as a trigger by sending waves constantly which are only picked up by nearby devices, while also listening for waves it can pick up to alert its user.
