The new Covid 19 contact tracing app has cost €850,000 so far to develop.
The long waited HSE app is set to be launched this week if it's approved by Cabinet.
It's been undergoing a trial period for the last number of weeks. Members of An Garda Síochána have been testing the app because they were one of the few groups that could move freely around the country.
The app will work via Bluetooth and will let people know if they've come into close contact with a positive case.
There have been privacy concerns surrounding the app, but the HSE says data will be stored on people's phones and it won't be shared with a government server.
Tech Correspondent Jess Kelly says it works by analysing how long your phone is in the presence of another person's phone who has also downloaded the app.
"If your phone is in close proximity to my phone for a prolonged period of time, which we understand to be around 15 minutes or more. And you are subsequently diagnosed with COVID19, a notification will appear on my phone. The contact tracing team will contact me saying you've been in close contact with somebody who is now a confirmed case, you should self-isolate.
