Because of its focus on tide and currents, it is best for kayak, canoe and SUP paddlers who get out on coastal waters.
The at-a-glance display of the multiple conditions makes the app a great tool for people who want to see good times to get on the water. The app flags gold star days/hours and warns of upcoming wind, heat or tide events that could get in the way of a good time.
By having a 10 day forecast, people can plan outings together - or you can block out some time on your schedule to build recreation into your weekly routine.
Some launch locations are near accurate current predition stations. Quick access to wind, tide and currents can make it easier to pick good times to paddle through channels or pick the right direction to ride the tide on single point trips.
The app is not a replacement for detailed current charts, however, particularly for longer duration journeys that will go through multiple waters. In the Seattle area, for example, it will help you plan the right time for a crossing to Blake Island but if you are exploring on a multi-day trip in the San Juans, you will want more comprehensive planning tools.
There are several ways that current stations report their predictions. The app correctly processes stations that return 24 predictions of current direction and speed for each day. We will be adding more intelligence to handle other reporting formats over time.
Also, some stations are near a tide station but may return current information for flows that are not relevant for the waters that you will be exploring. This is particularly true for stations that are outside the mouths of bays or that return predictions for deep waters.
You don't have to select a current station for your launch site if there are none that add value to your planning.
We don't touch your data. No account or login is required and no data leaves your phone. We do ask that the app be given permission to read your location to simplify creating a launch site. The application needs a network connection to pull the weather and NOAA predictions but no personal information is sent on those API requests.
The application is free. Costs may change if there are charges imposed by the weather and water prediction data providers.
Right now, this is an iOS only application.
