Store ratings include star-only taps from in-app prompts, which skew high. The peak and recent figures come only from people who wrote a review, which skews low. Compare each against itself: the drop is the signal, and a big gap between the two usually means heavy rating prompting is masking unhappy users.

His the best stations behind a paywall

★ · v7.12 · Oct 1, 2026

Used to enjoy this app very easy to use, but unfortunately this year they hid everything behind a paywall so all the stations you were getting for free now you have to pay for. I will be deleting and finding weather elsewhere.

Less stations

★ · v7.10 · Aug 15, 2026

Been using sail flow for more than 15 years. Today I can no longer access any of the stations I always have without upgrading. Useless. Uninstalling. Way to go sail flow and put the screws to your most loyal users.

Nice

Used to love SailFlow

★★ · v7.08 · Jul 13, 2026

I have been a Plus user of SailFlow for several years and have grown to rely on its information, however, when it automatically renewed last week I could not access any of my favorites for Hampton Roads as it said I needed to Upgrade to access them. SailFlow, you have just lost a user. I will be cancelling my subscription and moving to Windy.

Crashes constantly

★ · v7.05 · Jul 1, 2026

Current version of the app crashes whenever I go into the menu to change settings or preferences.

Someone f-ed it up please fix it, use to work perfectly

★ · v7.05 · Jun 11, 2026

Someone updated it ? Fed it up, it worked perfectly for years why now?

Upgrade is a fail

★ · v7.0 · May 14, 2026

The graphics are terrible and hard to see

Sucks!!!

★ · v6.38 · Apr 14, 2026

I purchased the $49.00 a year and it turns out where I sail mission Bay in San Diego you need a Pro subscription? Anyways a total waste of money.

Works great

Diametrical apposed forcasts

★ · v6.29 · Sep 16, 2025

Diametrically apposed forcasts , almost 180 degrees incorrect in San Diego at times

SailFlow Wind Forecasts Worthless for Lake Michigan/Chicago

★ · v6.27 · Aug 11, 2025

Typically the windspeed has been 10-15 kts higher than the SailFlow forecasts since at least early 2024, for Lake Michigan near Chicago e.g. the Harrison-Deaver GLERL buoy. One might think that the forecasts would be corrected after proving worng, but not so: The low forecast vs. high actual windspeed often persists for days on end. I have set a reminder to cancel my subscription before it renews again.

Reset password does not

★ · v6.24 · Jun 16, 2025

For $22/mo this app should work better. I recommend staying away from this app.

Often does not load so is unusable when that occurs

★ · v6.23 · May 6, 2025

When clicking the SailFlow icon on iOS the app often attempts to load and then cuts out returning the user to the icon. Not sure why this occurs but it is very annoying

The opportunity

What would it take to build a viable competitor, what would it cost to run every month, and a prompt to get started. Generated from the reviews on file; one LLM call per brief. Set ANTHROPIC_API_KEY for a real brief; the stub only fills in a template.
