Solution Platform

Our end-to-end technology solution includes three components:

  1. App: User-facing and customized mobile app
  2. Portal: Web-based administrative portal, and
  3. Servers: Server-based verification and key management.

Portal App Platform


Smartphone apps that use the private and anonymous Google-Apple Exposure Notification (GAEN) protocol, with production API access for multiple jurisdictions in and outside of the U.S.



A complete and rapid feedback loop from public health authorities to individuals, offering details about the risk of exposure to infectious disease and next step recommendations so that people are empowered to make informed decisions.



Our trusted science-based platform has gone through rigorous testing, from signal strength calibration to fine-tuning of an original dynamic risk scoring model.


Smartphone App

Our WeHealth Arizona app was one of the first exposure notification apps piloted in the United States using the Google Apple Exposure Notification (GAEN) API.

Our apps use anonymous, temporary, Bluetooth Low Energy (BLE) signals to determine physical distance between two smartphone devices all to help stop the spread of COVID-19 and other infectious diseases.


WeHealth Arizona

Made for the State of Arizona, with customizations for counties, universities, and tribal nations.



WeHealth Bermuda

Made for the Island of Bermuda in partnership with the Bermuda Ministry of Health.

Web-based Portal

The Portal enables public health officials to perform administrative functions:

  • Securely generate and deliver anonymous COVID-19 diagnostic verification codes for people who tested positive
  • Customize and rapidly update mobile in-app messaging to include accurate and localized health recommendations
  • Get anonymous mobile app use analytics in real-time


Verification and Key Servers

The server-side functions are split over two distinct server components: the Verification Server and the Key Server, and integrated with our Apps and the Portal. Our platform is fully compatible with Association of Public Health Laboratories (APHL) national key and verification servers.

Verification Code Delivery

WeHealth speeds up test verification code delivery by integrating with existing systems to make the process easier for public health professionals and patients alike. For example, via API access to the verification servers, our partners can generate and display a code directly in their patient portal UI alongside a positive test result.

Verification Server

This server provides and validates secure codes to verify diagnoses. Through the Portal, authorized public health officials (i.e. case investigators and clinicians), can generate codes, then distribute them to individuals for anonymous entry into the App.

The App then communicates directly to this server to validate the authenticity and expiration date of a code, and to exchange it for a certificate that allows secure transmission of a contact exposure key to the Key Server.

Key Server

This server communicates directly with the App to allow temporary exposure key data uploads that the App can share via Bluetooth during a period surrounding a verified positive diagnosis (it is authorized by a valid code from the Verification Server).

Each day, the Key Server packages and signs all newly uploaded key data and makes it available for download by the App user. This allows the App to compare exposure keys to key data previously captured by the App to determine if the user had a potential exposure – which would result in a local Exposure Notification.


Solution for Everyone

WeHealth partners with public health experts, governments, and communities to offer a state-of-the art solution to connect people with trustworthy, timely, and actionable notifications, resources, and recommendations to stop the spread of infectious diseases like COVID-19.
