Comments on SailFlow: Marine Forecasts for Android
★★★★★Charles Albrecht· May 28, 2026
A great tool in the kit for planning adventures on open water adventures.
★★★★★Gabriel· Dec 2, 2025
Incredibly detailed and accurate forecast. It's the only wind forecast I trust. Tide forecasts could be more accurate. Being able to add tide forecast to the hourly table would be nice too.
★★★★★Joseph Lapp· Jun 9, 2024
Great help preparing for a day of sailing
★☆☆☆☆Randy Farber· Sep 2, 2021
Been using this app for 10 years App always had an upgrade feature, but the app has ads so most weather stations were free to use for current condition and forecast. Now the greedy developers made any feature an upgrade. All stations say experimental and can't see anything. Just used this app like a month ago. Used to have 4 stars now it's 1.
★☆☆☆☆R L· Dec 30, 2021
I just paid for the upgrade to pro, and I see absolutely no difference between what I was using for free and what I paid over $100 for. Anybody else has a similar experience?
★★☆☆☆Alan Allegret· Mar 1, 2023
Loading times are horrible since the wind graph includes forecast models in it! 10 to 15s of frozen screen every single time you open a station. It's making the app painful to use. I'm now looking for better alternatives...
