The development process of the COVID Tracker app began on 22 March 2020 when the Health Service Executive (HSE) contacted Waterford tech company NearForm to build a contact tracing app for Ireland using existing Bluetooth technology in smartphones to support contact tracing.[6] The €850,000 project involved representatives from the Department of Health, the Economic and Social Research Institute (ESRI), the Garda Síochána, the Irish Army and Science Foundation Ireland.[10][11] NearForm was originally working on a centralised app that would group users' data together for authorities to study,[12] but in May 2020, the development team contacted Apple and Google to secure beta access to the Exposure Notifications System (ENS) developed by the two companies, which allows the COVID Tracker app to guarantee the anonymity of users and ensure any data transfer to contact tracers would happen only with user consent.[10][13][14] Within three months of development, the team had a secure, tested and reliable contact tracing app that worked and was ready to be deployed on a national scale.[6] The COVID Tracker app was launched by the Government of Ireland and the HSE on 7 July 2020 with 862,000 downloads on the first day of launch.[15]
On 19 October, the COVID Tracker app became one of the first wave of national apps linked with other countries across the European Union after being linked with similar contact tracing apps from Italy and Germany.[22]
Any phone users are in close contact with that also has the app installed.[24]
The distance between users' phone and another app users' phone.[24]
The length of time users' phone is near another app users' phone.[24]
Every two hours the app downloads a list of anonymous codes which have been shared with the Health Service Executive (HSE) by other people using the app who have tested positive for COVID-19.[25] If a user have been closer than 2 metres for more than 15 minutes with any of these phones, that user will get an alert notification on their phone.[26][27]
The app requires users to turn on the Exposure Notifications service and will only be available to those with phones running Android 6.0 Marshmallow or higher, or iOS 13.5 or higher.[28]
Privacy and data
The Health Service Executive claims that the COVID Tracker app protects the privacy of all users and was designed to protect users' privacy.[29][30]
On 9 August 2020, it was announced that the HSE was working with Google to identify and fix phone battery issues after the COVID Tracker app was reportedly draining Android users' batteries in 5 hours.[36][37] On 10 August, it was reported that 10% of Android users (86,000) uninstalled the app, following battery drainage issues.[38][39] On 11 August, the HSE announced that an update had been rolled out to 70% of Android phones, which is expected to fix the issue, and that 45,000 people had reinstalled the app in the last few days.[40]
