v2.5 released 5 June 2023 (Major update to the wave height algorithm, to more accurately reflect wave heights through each hour of the forecast. Each hour forecast also now includes a rating from 0 to 5 stars, which takes in to account the waves, swell, tide and wind data for that time, as well as recent wind conditions and the direction of the coastline. More detailed star ratings can be shown by tapping on the forecast chart, which will display the extra data just above the chart).
