Why make out to be free?

Another company going the route of offering a free app that has literally 0 functionality unless you pay. FU.

Developer Response ,

That's very harsh. I feel your frustration and I wish I was the size of Google to offer free functionality. The reality is I'm just one guy giving up his weekends and evenings to build the best experience I can for drone pilots and I don't see why I should have to do it for free. It's a specialist niche product so it's not going to sell thousands of units and not to mention the data is pro-level and costs money too. It's reviews like this that make me want to quit the app store and give up being a developer - I've spent *hundreds* of hours on Windsock only for you to swear at me and give it 1 star. If you'd like free functionality you can actually use the app for free for a week and cancel before the week is up and it won't cost you anything. Please do give it a try and if nothing else please consider changing your 1 star rating.

Great app for many activities sensitive to wind conditions.

Previous versions of this app offered little more than a good weather site does, but this release is a whole different beast!

This app is valuable for anyone who does activities sensitive to wind conditions, like flying model aircraft. The app allows you to specify the activity you do so that the icons in the forecast can give you contextual information about how the weather affects you activity, such as too much or too little wind and temperature conditions affecting battery performance.

The latest update looks great and gives me all the information I need.

Saved a journey

I fly model gliders on a slope about forty minutes drive away. Having this app with a location chosen next to the flying site enables me to see immediately what the wind strength and direction is and whether it is worth making the trip. Easy to read with forward projections to check if conditions will get better or worse. Sometimes a change of wind direction or strength can make the decision for you whether to load up and drive to the site. Great.
