Met Éireann Weather Ireland is a free iPhone application developed by FUSIO under the Lifestyle category with a focus on weather updates and forecasts. The app is a complete weather companion for anyone in Ireland who wants to stay updated with the latest weather conditions and forecasts. With Met Éireann Weather Ireland, users can check for any active weather warnings for the Marine, National, and Environmental sectors.

The app offers interactive animated maps of rainfall radar, rainfall, temperature, wind, and pressure forecasts for up to seven days. The high-resolution rainfall radar updates every five minutes, and the rainfall, temperature, wind, and pressure forecasts are derived from high-resolution Numerical Weather Prediction models. The app also provides an outlook for the next seven days with a brief overview of the expected weather for any location in the country.

Moreover, the app utilises the GPS functionality of the user's mobile device to provide a seven-day detailed forecast for their exact location. Users can scroll through the detailed forecast and examine the forecast for expected warnings, weather, temperature, wind, and rainfall amounts. The app also provides the latest weather observations near the user's location and the National and Regional Forecast for Today and Tomorrow, including animated maps displaying the forecast weather, temperature, and winds.
