Dr. Tomás Ryan:

The app itself is an excellent piece of software. It is one of the success stories of Ireland's pandemic response but it is not being used widely enough. Studies early on in the pandemic showed that electronic contact tracing, which is a very powerful tool for supporting contact tracers, is most effective when most of the population is carrying it but we just do not have that at the moment. Dr. McConkey has proposed many times that we should find ways of giving smart phones to everyone in the population who does not have access to the app. If everyone was carrying this app actively, it would make a huge difference.
