Won't open in my iOS 9


First, after not using it for 6 months, it disappeared as an app from my phone. When I downloaded it from the cloud again, it only opens for 2 seconds, then disappears, reverting to the home screen. This happens each time I try to open it even after shutting the phone down and restarting. Deleted it and redownloaded-same thing.
I don't want iOS 10 or 11 because I've got some old apps. It says it's supposed to work with 9 or higher.

SauTag, bookmark on your phone's browser(s), and use it instead of the app. Same username/password. Yours is a rare case where an occasional user with a very old iOS version will run into that bug. We respect your desire to not upgrade your iOS, though we will be here for you when you do! For now, is more than a sufficient replacement-- it's terrific on your phone's browser.

Recently began to use SailFlow after using Underground Weather for a couple of years. Very user friendly and gives updated wind and tide information wherever you are sailing which is very useful. I will stay with SailFlow.

So many weather markers


Love this app. There are so many weather markers accessed. There’s multiple stations on Galveston bay and numerous around Houston. I find their forecast fairly accurate.

Thank you, Geojak. We'll never stop improving our weather station network on the Gulf Coast, and beyond!
