I find this criminal and will file suit against this ridiculous company. -- ServiceSucks123, 2024-12-28 ### **--- "Overpriced and disappointing upgrade" I recently upgraded to the SailFlow Plus plan, but I’m incredibly disappointed. There’s absolutely no noticeable difference in service between the free version and the Plus plan. While the app itself is decent and has potential, it’s frustrating how they gatekeep the most useful features behind an overpriced Premium plan, charging over $150 a year! All I want is to check my local wind stations and see basic details about wind conditions—nothing fancy. That should not require spending over $5 a month. The app could be great if it offered more value at a reasonable price point, but as it stands, it feels like a cash grab. 2 stars for functionality, but the pricing structure is a dealbreaker. -- airborne21n, 2024-12-27 ### *---- "version 6.15 crashes on iPhone 17.6.1" Nothing worse than an auto updating app that crashes on launch. device is an iPhone 11 pro Tried deleting, then reinstalling, but the app crashes when searching for a city Not a confidence builder when you depend on weather for your days safety. Other choices, and backups, sure. The app shouldn’t crash -- SteveOf2, 2024-11-15 ### ***** "Help - wind speed is no longer in kts" Overall this is a great app. After the version 6.13 update, the wind speed on tables and graphs is in mph (even though my settings are for knots). Update: Issue corrected in version 6.14. Thanks for the rapid fix! -- Sue with 3 cats, 2024-10-04 ### *---- "Map and zoom" Latest update is really messed up - all favorites lost, zoom controls cause map to jump around the world. Requires two fingers to zoom in but jumps back to prezoom intermittently. Is there anyway I can rollback to a previous release? Gary -- GaryDickens, 2024-09-12 ### ***** "Free Version = Better" Free version is better…it said it was gusting 2 and sustaining 20 knots though…It was blowing 4kts maybe.overall pretty good. I love it so much. SailFlow>windy.app -- R.I.P Mitch(come back), 2024-09-11 ### *---- "Latest update made it unusable" After using this app for a couple of months, I recently purchased a yearly Premium upgrade. Less than 2 weeks later an update was issued and the maps and weather stations, in my area of Alaska, don’t function correctly. Some stations don’t even show up on the map, and I can’t zoom in to an area smaller than the US. I would like to get a refund. -- rvtrvlr1, 2024-09-05 ### *---- "Absolutely unreliable" 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 -- Azredhd, 2024-08-04 ### *---- "Direction arrow is still wrong!" 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. -- Truthteller863839, 2024-06-29 ### ***** "Great weather application." Very accurate. -- WC1320, 2024-06-22 ### ***** "SailFlow" Great app and super accurate and easy to use. I had questions concerning billing and the question was handled in less than 6 hours and explained to me thoroughly! -- SatbeachDev, 2024-06-13 ### *---- "Update broke app" 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 -- Helakarma, 2024-06-13 ### ***** "Great information." We love the marine Wx forecast attached to this app. Quick and efficient. -- Aero WX map, 2024-04-23 ### ****- "User friendly" Great app & easy to use -- poeg eyed panzies, 2024-04-17 ### ***** "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. -- MQDean, 2024-03-15 ### ***** "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. -- 5820tir, 2024-03-11 ### ***** "Great App" I use it to monitor my areas before boating days. Very accurate and simple. -- AJCuebas, 2024-03-09 ### ***** "Captain of Freda Mae race boat" Excellent -- Frada Mae, 2024-03-01 ### ***** "Great for sailing days and every day!" I use the app every day for accurate hour by hour forecasts along with radar and wide area view of all the local wind/weather stations you have an amazing on the ground view of what’s in store for your day -- sattva.guru, 2024-02-23 ### ***** "Great so" A part of my forecasting toolkit. -- 2dasea, 2024-02-05 [View all SailFlow reviews and detailed analytics on AppTail](https://apptail.io/account/signup?utm_campaign=ai-crawl&utm_content=reviews) ## SailFlow In-App Purchases | Item | Price | |------|-------| | Pro | $119.99 | | Gold | $179.99 | | Plus | $44.99 | | Pro -
