ReopenCU COVID-19 Symptom Self-check App

Follow these instructions to download and use the ReopenCU COVID-19 Symptom Self-check app.

You must have a green pass from the app to access campus buildings.

Users who do not want to change their app store location to the U.S. should use the web version.

The first time you use ReopenCU, the app will request permission to use location services the first time you open the app. Enabling location services is voluntary, but will improve contact tracing at Columbia by providing access to the SSID of your wireless network connection. Note that this location data will only be used for contact tracing purposes to identify potential close contacts.

Data will only be collected when the ReopenCU app is open and you are connected to a Columbia University wireless network.

Make sure you are using the latest version of the app by updating it in the App Store or Google Play.

This data will be used to identify you and a timeline of the WiFi access points that your device has connected to, allowing the University to more precisely track potential exposures to COVID-19. 

Opting in or out of location services is your personal decision. If you do not enable location services for the ReopenCU application, you can continue using any of Columbia’s wireless networks and the app will not collect your data. 

You can also enable or disable location services manually through your iPhone or iPad settings or your Android device settings.

The ReopenCU app is available for download from the App Store (for iOS devices) and Google Play (for Android devices). Be sure to visit the Symptom Self-checking page for more information about using the app.

Open the app and log in with your Columbia UNI and password.

The Attest tab provides the daily symptom check.

The questions come from the New York State Interim Guidance For Higher Education Research During the Covid-19 Public Health Emergency and can be read by clicking on the link at the bottom of the symptom check form.

Answer the questions and click "Submit."

Everyone who returns to campus must sign the University Health Compact, take safety training, and get a COVID-19 PCR test.

  • The app allows you to digitally sign the compact; select "Show/Hide Compact." Once you select "I Agree," the app will remember your choice.
     
  • Once you have completed the appropriate safety training, the app will update to reflect this change, but this process can take up to an hour, so plan accordingly.
     
  • After you have taken a Columbia Test and Trace program COVID-19 test, the app will also reflect this information. Compliance data is regularly transmitted to update the app, and in most cases will reflect within 72 hours, often faster.

The boxes in the ReopenCU app are updated once you finish the compliance steps, following the timeline described above for each.

If you need assistance with the app, contact the CUIT Service Desk: Submit a ticket, email [email protected], or call 212-854-1919.

Students will then be asked to select "Morningside" or "CUIMC" and be routed to the appropriate student health portal to upload proof of vaccination. Employees will see a form that asks for basic data about vaccination and allows uploading of one documentation file in either jpg, jpeg, png, or pdf format.

You must complete all fields before clicking "Submit" to upload your documentation.


Requesting an Exemption

Students can request a medical or religious exemption through the appropriate student health portal, Morningside or CUIMC.

Employees can request an exemption for medical or religious reasons by selecting the "request exemption" checkbox. The next page provides information on how to submit the request. Reviews will be conducted by a panel of medical experts including a representative from Human Resources. If the exemption is granted, the My Checklist section of the app will have an automatic check mark.

Once you click "Submit," the app will generate a date- and time-stamped 24-hour certificate. Assuming you have no symptoms, this daily pass will be green.


If you answer yes to any one of the questions and receive a red pass, you should not come to work and should notify your supervisor.


Your daily pass is available at all times on the Pass tab found at the bottom of the app screen.
