Absolutely unreliable

Azredhd on

United States

I have been trying to use the current and forecast map for the last week and every time multiple times a day the “current” conditions are over 8 hours in the past. In addition, even though I have the most premium paid edition, there is an ad that is triggered at the bottom of the screen while trying to get the forecast animation to play (which doesn’t). I have had to resort to using other apps to get the required information. TERRIBLE

Direction arrow is still wrong!

Truthteller863839 on

Update#2: [My comments] The developer responded, saying “ Wind direction is always reported on where the winds are coming from. [Yes, a SW wind comes FROM the SW and goes TO the NE] The arrow vectors show the direction of the flow [I.e. the arrow points TO the wind’s destination, not its origin] , they are not meant to be wind barbs. A North wind means winds are coming from the north, a conventional 'wind barb' will point into the wind, North, and a wind vector will be aligned with the tip pointing south." [They proved that their arrow vectors point in the direction the wind is flowing TO, not the direction it’s coming FROM. I’m just asking that they fix their app to say Direction To rather than Direction From, not changing anything but the text. Keep the arrows pointing as they are, just label them correctly!!] Update: this issue is still broken. It should be a simple fix, and contrary to the reply from SF, it’s not a matter of opinion, it’s the truth! It’s a confusing error and should be fixed ASAP. ************************ In general the app works well, but there’s a problem with the Observed wind direction shown on the Wind Graph page. It’s pointed in the right direction, but it’s labeled wrong!! It’s labeled in the key as “Direction From” when it’s actually the direction the wind is flowing to, not from. I’ve emailed the developers directly but they’ve never corrected it. I know it’s a small detail in an otherwise useful app, but it seems like an easy fix to remove any confusion.

Great weather application.

Update broke app

Helakarma on

Use SailFlow for work. Latest update causes app to freeze and become unresponsive. Support had an attempted fix but it did not work. Will update review once problem is corrected

Great information.

Love it

I row in SF Bay out of an exposed location that receives the fury of the wind through the Golden Gate Bridge. SailFlow is very valuable allowing me to know ahead of time the conditions I might be encountering when I arrive at the dock. SF is a MUST for safe open water rowing.

Most Accurate Weather Forcast

I live on the Chesapeake Bay and weather from local stations are for inland and doesn’t seem to be very accurate. Marine weather is very different. I have noticed that this app is correct most of the time. As a boater I use this constantly.

Great App

I use it to monitor my areas before boating days. Very accurate and simple.
