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

More location-specific forecasting

You get weather specific to a more precise area. WU might give you a general forecast of rain and thunderstorms, which might be true somewhere in your forecast area, yet miss the mark for where you wish to sail. That’s weather in Florida! This app forecast the thunderstorms about 3-4 hours later for my vicinity of interest and was on the money. So this app is more helpful when you need a window of just 1-2 hours. If this app said thunderstorms or too-strong wind conditions were imminent for my vicinity/time of interest, I wouldn’t bother to try sailing that day.

We appreciate your vote of confidence, Barbershop Brad!

Even this new sailor gets it

So, I have exactly a 2 day adult beginner sail class under my belt. I now need to schedule a check off ride but with winds above 5mph and below 16 mph. I find this app and in completely accurate, understandable graphics it tells me current and forecasted windspeeds exactly where I need to test. The big day is tomorrow! I know this because I used the app and reserved the slot. I will use it in the future to plan my sailing days. Great job app programmers!
