Pros and cons of SailFlow: Marine Forecasts app for iPhone and iPad

SailFlow: Marine Forecasts app good for

Fantastic app! The wind predictions are generally dead on. I use it every time I go sailing on Lake Ontario.
Always enjoyed this app, have been using it for years. I sail my 21 wooden catboat from the Cape to Connecticut and always use for wind and trends. It is no match for ole noaa handheld radio but I enjoy other the features and has always been impressed with their reports
I sail out of the Milwaukee Community Sailing Center and use this app before each sail. I also use it to plan for trips involving guests. Although weather conditions change, the info this app provides is consistently helpful. At first, it does take a little work to set up a relevant "Favorite," but once this step is accomplished, checking the forecast for the weather near the MCSC is really easy. A great app.
Im a late bloomer in sailing and am constantly striving to improve. This app shows wind direction, speed and even wave height, frequency, etc. It took me a bit to configure it to how I like, but its worth the learning curve. Sure you can get a lot of the information from NOAA buoys, but here its all in one place. I definitely suggest trying it out.
Seems to work ok I am not fully aware of all features. Wish I could figure how to set my home port of Goderich and not have to zoom in from North America
As a professional mariner I am always interested in the weather, especially what the wind forecast is. This app in combination with other resources is a valuable tool.

Some bad moments

Complcated, counterintuitive. Kept trying to sell upgrade. website is even worse. Uninstalled within 3 minutes. Why would it want my location when not even on?
I have been repeatedly disappointed by the inaccuracy of wind forecasts. Period!!
Sail flow is a great app on my Mac but does not work on my iPad
Buggy. On a good day it will work fine 2 out of 5 times. Havent had a good day in a week. Currently it crashes every time I try to open forecasts. Every time.
Keeps ejecting the user back to the desktop. Very poor layout. Not working.
The app constantly crashes whenever opened. Makes the app useless.
