Stop COVID-19 with NOVID.
NOVID is a next-generation mobile application with Pre-Exposure Notifications which allow users to proactively make decisions based on their risk of infection. We are the only mobile solution with:
An Early Warning Network
Sub-meter contact tracing accuracy
Works without being open
Complete anonymity
Tools for communities and institutions
Tools for health and testing providers

How it Works
Hear from our founder, Po-Shen Loh
Pre-Exposure Notifications
Visualize your risk of exposure
NOVID anonymously detects when you are close to other users by using a combination of ultrasound, Bluetooth and Wi-Fi technologies.
By tracing interactions, NOVID builds an anonymous network of your connections. We help you understand the spread of COVID-19 around you by visualizing cases in your network of interactions.
This places a COVID-19 forecast into your hands. If you see that the virus is approaching you through your network, you can proactively take precautions to keep yourself and those around you safer.
Sub-meter Detection Accuracy
Avoid false exposure alerts
Most other apps rely on Bluetooth or GPS. Bluetooth- and GPS-based technology are not accurate enough for measuring distance between users. These signals pass through walls and floors, falsely recording interactions between people who are actually physically separated.
NOVID combines ultrasonic technology with Bluetooth to detect your interactions. Ultrasound gives us much more accurate data, since it reacts with materials organically and won’t pass through barriers like walls. In a systematic study, we found that we avoid falsely recording interactions with 99.6% accuracy.
We display distance measurements on our app interface for full transparency. Try our distance scanning feature with a friend or family member to test our accuracy yourself!
Background Operation
Stay safe and informed while multitasking
On Android, ultrasound, Bluetooth, and Wi-Fi scanning work seamlessly in the background. This means that we detect your interactions with high accuracy even if the app isn’t open.
On iOS, NOVID works best while open. Standby Mode allows you to keep NOVID running while preserving battery life. Background Wi-Fi Mode enables iOS devices to detect interactions seamlessly in the background, but not at the same level of accuracy as ultrasonic scanning. Phones connected to the same Wi-Fi access points for prolonged periods of time (several hours) will be counted as having interacted.
Completely Anonymous
No username, password, phone number, or email
We don’t collect any personal data. No username, password, phone number, or email. We’re serious about privacy. We don’t know who you are—and it’ll stay that way.
We require Bluetooth to communicate with other devices, and Microphone permissions to receive ultrasound. On Android phones, Google requires that we ask for location permissions in order to use Bluetooth. We never use location data; we just need the permission in order to use Bluetooth due to policy.
We use encrypted and anonymized data. Nothing we store can be traced. We’ve designed our system from the ground up so that our data only has value to you, the user, once transmitted to your phone.
Made for Communities
Fight the spread together
Admins of organizations or institutions can create “communities,” or virtual groups of NOVID users. Community members can opt-in to share their anonymous data. This reveals previously unattainable community trends about the spread of COVID-19. Admins and community members with access to this dashboard can see these trends to make better-informed decisions and keep your community safe.
Communities can create check-ins and positive cases linked to specific locations using NOVID QR codes, called “GeoTags.” Admins and community members with access to GeoTags can view them in an interactive map interface to see buildings or places with positive cases, and buildings that need to be sanitized.
Official Testing
Verified self-reporting is here
NOVID enables hospitals and health authorities to anonymously verify self-reported cases of COVID-19 from the application. Users will receive exposure notifications that specify whether an exposure is verified by a trustworthy health authority administering official tests, or is self-reported.
Health officials at hospitals and health centers can access a simple interface that generates tokens for patients to anonymously confirm their status in the NOVID application. This lets the people around them know they should take the report seriously, and start to be vigilant.
