Same problem as Sautag

Had exactly same thing happen and it locked up asking me to upgrade to Pro. Won’t let me in on free version. Don’t use enough to warrant fee for extras. Was good the way it was.

Great app to see weather conditions at a glance. The forecast helps me plan my fishing trips. I know when to go and most importantly when not to go.

His the best stations behind a paywall

Used to enjoy this app very easy to use, but unfortunately this year they hid everything behind a paywall so all the stations you were getting for free now you have to pay for. I will be deleting and finding weather elsewhere.
