Bathing Water is a free Android app developed by DHIgroup, listed under the Lifestyle category and the Weather subcategory. It provides information about the bathing water quality and weather at selected beaches in Denmark. The app shows the location of the beaches on the map, and the flags display the current water quality status, with green indicating safe and red indicating not recommended for swimming. Users can get the bathing water and weather forecast for up to three days by clicking on the flag. Additionally, users can choose their favourite beaches from the list and mark them. However, the app only shows marine beaches in municipalities subscribing to the Bathing Water Forecast.
