### 5/5 — Great app improved lately

*2026-08-27, version 7.10*

It’s working well with a lot of recent fixes. Love the Apple Watch integration where you can view the wind on your watch face. 
One thing though. An app called iWindsurf should not have wingers on the splash screen!

### 5/5 — My go to source for wind updates and forecasts.

*2026-08-12, version 7.09*

Read in the morning, same in the evening. Peruse throughout the day.

### 5/5 — Great for planning fishing trips offshore

*2026-07-21, version 7.08*

Excellent application

### 5/5 — Amazing app - very accurate

*2026-07-09, version 7.07*

I love iWindsurf it is the most accurate wind app out there …

### 1/5 — Wind Forecasts

*2026-06-28, version 7.05*

They no longer show. Just a blank topo map. If you toggle around between models you can get something to show but sometimes it is by the hour, sometimes every 4 hours. Come on guys! Used to be great. Now just an exercise in frustration. I am about to give up my paid subscription.

### 5/5 — Session saver

*2026-06-24, version 7.05*

Ive been running my school since 2003 using I windsurf and I kitesurf as go to source. Successful sessions are planned; some are spontaneous... relying on up to date accurate forecasts ! Thank you guys for all you do to maximize information availability !! Laurel Kaiser  Island Style Watersports

### 3/5 — More sensors and fewer forecasts

*2026-06-24, version 7.05*

I have been paying for iWindsurf for years. I do like the sensor data for Sites on the Columbia river Gorge. However, the forecast are not as useful as they used to be. In the past, there were two forecast a day and each of them indicated the time that they were posted. Now there’s just one forecast today and since the time is not recorded, I suspect that the forecast from the day before may simply be copied over to the next day. Maybe I’m wrong. But I wish the forecast would indicate the date and time that they’re posted.

### 5/5 — Great app

*2026-06-10, version 7.05*

Nice historical data and forecasting

### 5/5 — Great for wind!

*2026-06-06, version 7.05*

Great for wind!

### 4/5 — Strong App - Minor Bugs

*2026-06-06, version 7.04*

Good app, very helpful for predicting windswell for surfing the Great Lakes. I like being able to demo different models. Sometimes it loses my favorites but seems to happen less often. Could use larger font on the maps.
