iWindsurf Customer Insights

1. For me, sailing in the gorge, the pro forecasts and live sensors are indispensable.Despite having a fully paid subscription to windalert, I note the forecast information is gone.

2. What a ripoff when I already have a fully paid pro account.iwindsurf human Pro forecasts dictate my day.

3. This was a heavily use app for me.free version is ok but upgrading for the wind stations, forecasts and real-time data I actually want doesn't work.

4. I am rarely let down by iwindsurf in choosing my windsurf gear for the day - or deciding to grab my mountain bike instead.Used it for a few years now.

5. The forecasters have tremendous experience interpreting the various computer models for the highly complex microclimates of SF Bay, giving accurate predictions and reliability expectations.

6. Now I have to get the wind reports from the iWindsurf website.One of several apps that seem to have this identical, terrible interface.

7. Other than that, I love this app!I've gotten great value from iwindsurf over the years.

8. Why did you guys break a totally good app?? Keeps crashing Even after update, same problems! (4/17/23)The app no longer works on my android like it did.

9. What happened to the wave height portion of the app? Am I missing something? I recently had to uninstall & reinstall the app and now the wave portion of the chart isn't there.

10. Even their feedback form is broken and won't let me submit it without selecting something from dropdown menus that don't show up.

11. Won't be left in the rain.After the update, app crashers every time it's opened.
