Windsock is an advanced weather app for professional fliers of drones and other UAVs. As a pro perhaps you've already found that packing the flight gear and driving down to the flying location only to find it's too windy to fly can be frustrating. Instead, use these tools get comprehensive reports on the latest flight conditions for a nearby location so you can feel confident that it's great weather at sunset for flying or even if it's great right now - find those perfect flying weather windows and fly smarter!

Get access to premium data that uses the power of satellites, radar and local weather stations all over the world to deliver advanced wind and condition forecasts for your favourite drone flying sites. Let's be clear, this isn't one of those basic freebie weather apps! Windsock tracks over 17 forecast metrics from multiple aggregated data sources. Forecasts are up to 7 days in advance with high-resolution forecasts every hour on demand for almost anywhere in the world.


17 forecast metrics - displayed in 5 easy to understand data panels - summary, visibility, air, precipitation and satellite.

Grab forecasts for your current location without even having to add it as a site.

Generate a full audible report of the current conditions and have it read out to you hands-free, just shake your device if you have location enabled.

Quickly find out when sunset is so you know exactly how much daylight you have remaining.

Forced to subscribed = deleted

Even though it may be “free” for a week, don’t bother downloading as you can’t use app without subscribing to a rather pricey subscription. You can’t even evaluate app without subscription to the app. Useless app for evaluation in its current state as I shouldn’t be forced to subscribe to a potential bait and switch scheme.

There are many apps that give me what is in this app for free. I use AirMap and UAV forecast that do not charge for my needs. UAV includes 48 hours forecast for free with altitude winds and AirMap, you can file FAA flight plans. Since I am near Charlie airspace near KJAN, it is a godsend to have an app with this file flight plan feature.

Developer Response ,

Hi Allen, I am sorry you had a disappointing experience. The app is not free as I spent hundreds of hours working on it in my own time and the weather data is a premium service that has to be paid for somehow. Other apps usually have adverts which harvest your personal data to track you across apps and/or track which locations you add. This could be unacceptable for you depending on your operational needs. If anyone is willing to sponsor a free version however... I'm open to it but some customers do prefer to pay a monetary price rather than pay for it with their privacy.

Windsock doesn't have ads. In fact it does not even have user accounts - you purchase via Apple using in-app purchases and I never even get your email address!

I do recognise that the App Store description probably wasn't as clear as it could have been about being a subscription-only app but you do get a free trial to evaluate the app with. I've added a line at the top now to highlight that it is subscription-only.

I'm glad you've found an app that works for you at least, stay safe and keep up the flying.
