SailFlow: Marine Forecasts users say on Google Play
This app gives you a straightforward map with the wind directions presented clearly. It displays them in a range of colors that correspond to the wind speed. There is a color to speed chart at the bottom to make it easy.
Recent update seems to have broken widgets. Widgets show empty. Great otherwise. Hello. The latest update broke them again.
App is okay, but holds back. Appears to provide false data unless I pay for Plus. Then local/likely data is suppressed unless I pay Pro. Adding features would be fair, but pushing questionable data unless I pay is not.
Not intuitive to understand or operate. However, I do like the historical averages chart (when I can find it for a chosen location). Paid version seems quite expensive. Going back to my other preferred wind app.
This app has hidden subscription and you ended up with closing your credit card. Because of no contacts. After then you receive messages about trouble of paying. Content displayed you can find online without this fuss.
