COVID Tracker is a free and easy-to-use mobile phone app that will:

  • alert you if you have been in close contact with someone who has tested positive for COVID-19 (coronavirus)
  • keep other app users safe by alerting them if you test positive for COVID-19
  • give you advice on what to do if you have symptoms
  • store your EU Digital COVID Certificate

Where to get the app

Download the free app from the App Store for iPhone or the Google Play Store for Android.

You should be able to use the app if your phone:

  • is less than 5 years old
  • uses Apple's iOS 13.5 or higher or Google's Android 6.0 or higher

You will need to confirm you are 16 or older. This is the digital age of consent.

You will need to have Bluetooth switched on for the app to work.

Alerting you if you are a close contact

You'll get an alert on your phone if you have been in close contact with another app user who has tested positive for COVID-19.

The alert will advise you to:

Keep others safe if you test positive

If you test positive for COVID-19, you can use the app to alert other people you have been in close contact with. This is done anonymously. No one will know that you have tested positive. But your close contacts will be able to take action to stop the possible spread of the virus.

Read about how to use the app if you test positive.

Track your symptoms

You can use the COVID check-in on the app to track any symptoms of COVID-19 you have and get advice about them.

It's your choice if you want to track your symptoms or not. You do not have to track your symptoms for the other functions on the app to work.

Read more about tracking your symptoms.

Store your EU Digital COVID Certificate

You can use the COVID Tracker App as a 'wallet' to store your EU Digital COVID Certificate securely on your phone. This can make it easier for you to carry your certificate with you.

To do this:

  1. Update your COVID Tracker App to the latest version.
  2. Scan the QR code on the certificate you get by email or in the post.

If you got your certificate by email, it's easiest to open it on another device. You can then use your mobile device to scan it.

The certificate is only stored on your phone. It is not shared with anyone. You can delete it at any time.

You can use the app to store your certificate without using any of the other features in the app. You can find out more about the EU Digital COVID Certificate on

Updating your EU Digital COVID Certificate

When you get your certificate with your booster vaccine, delete your old certificate and then add your updated certificate to the app.

To do this:

  1. In the COVID Tracker app, tap View EU Compatible Digital Covid Cert.
  2. Tap EU COVID Certificate detail.
  3. Tap Delete then Confirm.
  4. Tap Register EU Digital COVID Certificate then Scan EU Digital COVID Certificate.
  5. Scan the QR code on your updated certificate.

Protects your privacy

The app is designed to protect your privacy at all times.

It's always your choice to:

  • use the app, or not
  • decide what information you want to share, or not

You are never asked for your name or address. The app does not track your location. You will stay anonymous - other app users will not know who you are.

Latest news and information

You can use the app to follow the latest facts and figures about COVID-19 in Ireland. You'll also be able to get information that will help you to care for yourself if you are sick.

Put public health advice first

The COVID Tracker app has been designed to make the best use of the health advice and technology available. But it’s not perfect. It is part of a number of ways that we can slow the spread of COVID-19 and should not replace the existing public health guidelines.

It's still important to:

If you cannot use the app

The app is one part of our contact tracing operation. Our contact tracing centre is still open. Everyone is included in that process, whether you use the app or not.

We hope future versions of the app will make it accessible to more people. We are continuing to look at solutions to include everyone over the age of 16.

Using the app abroad

The app also works in Northern Ireland, Germany, Italy, Denmark, Spain, Hungary and Latvia.
