Tackwatch, a forecast that shows its disagreement
A sailing weather app that compares multiple wind models, maps their spread, and keeps forecasts available offshore.
Field notes
The proposed app compares seven named forecast model families and keeps their answers side by side at a selected map point, including wind, gusts, sea state, and a three-day trace. Its interface is designed for sailing: knots are the default, wave period and direction appear alongside height, and model run age stays visible. The project says forecasts can be cached or downloaded for offline use, with stale data marked clearly, but the page also says the app remains in development and is not yet on the App Store.
