Greater Good

Reduce the spread of COVID-19 when social distancing is not possible and save lives in your community.

Bluetooth Low Energy

Continuously scans in the background for nearby infected users when outside. Let's you know how many infected individuals you’ve been in contact with accidentally.

Once you install the app, it runs in the phone’s background. When you go outside for essentials or for an emergency and come in contact with an infected individual or an asymptomatic person, your phone gives you an alert so that you can take preventative measures like self-isolation before any symptoms appear.


Nearby Regions Heatmap

Identify nearby areas with high infection rates. Establish red and green zones to limit traveling into those regions.

Preventiv values the user's privacy. When a user inputs as infected, their geolocation is collected only to create a heatmap so that their community can stay safe.



Receive instant alerts when previous connections within the last 14 days become positive. Stay safe by taking preventative measures like isolating yourself and calling for medical help if you start to feel unwell.

Even when your phone is switched off, Preventiv works hard on the background to keep you safe and updates you with real-time notifications.
