Great app

They update enough to keep app working well. This app gives precise and unique info for guys like me that race sailboats where wind, waves and weather in general matter. Seeing all history, current and forecast weather is important for both safety and more so to be able to anticipate changes that give me an edge in competition! Thanks guys and gals.

We'll keep working to give you that edge, Bad Dog!

Love this FREE app

I use this app all the time with no problems. We used it to travel the ICW Atlantic this fall and it was our guide to our travel plans each day. Only reason I am giving it 4 stars is that on my iPhone (iPhone 6s) it displays the map and locations making it easy to use. When my husband loads the app on his iPhone 8 we cannot get the map to appear, even though we compared all our settings to ensure we were the same. He has the latest iOS loaded so not sure if it is an issue with the iPhone 8?
Would highly recommend this easy to use app and hope to get it working on the iPhone 8 with a Street / Wind map like it does on my iPhone 6s.

Hi RH. On your iPhone 8, you may have cellular data turned Off for SailFlow! On your iPhone, try going to the phone's Settings app. Tap Cellular. Scroll down to SailFlow and make sure cellular data is ON for SailFlow. You can also contact us at

Free version okay, don’t pay for upgrade!

Clunky and buggy but still has a wide range of stations and data beyond just wind speeds. However, none of the cool sounding features promised with the paid subscription actually work.

Support is responsive and polite but unable to fix the issues. After the standard wipe and reinstall dance they’ve got nothing. Not clear what the money is for, but it doesn’t really get you anything the free version doesn’t already have.

Edit: Free and broken is better than paying and broken but I don’t see how the dev response here has anything to do with the problems...

Developer Response ,

Thanks Scuzzmonkey. Have another look: We have a Free Trial running this weekend, giving everyone full access to our Pro Weather Stations - our large exclusive network of weather stations that we have been installing & maintaining in North America since 1987! Also, our Pro Forecasts for Pro members, and Plus Forecasts for Plus members are significant upgrades, and are fully available right now.
