MetService Marine is a free iPhone application developed by the Meteorological Service of New Zealand Limited. This app provides recreational and coastal marine forecasts, severe weather information, tides, 7.5-minute rain radar, 3-day rainfall forecast imagery with wind barbs, surface pressure maps, user-selected default location, and the ability to change the background image with your favorite fishing spot.

The app is designed for smartphones and requires iOS 7 or later. It does not provide surf and beach forecasts or marine maps that are not included in the list above. With its easy-to-use interface, MetService Marine is an excellent option for iPhone users who want to stay informed about the weather and tides on the go.
