Frequently Asked Questions

Windsock stopped working and is now asking for a subscription?!

Windsock 2.0 was launched end of 2013 and unfortunately as popular as it was, it made a massive loss. It used the best weather data available which sadly isn't free and every time a forecast was fetched it had a cost associated. While the original app was priced to include a casual amount of usage over the lifetime of the app version (1 year being the expected lifetime), it was a business model that sucked. The more usage Windsock got the more its costs started to spiral and so I had to regrettably remove the app from the store mid-2014.

However many loyal users had paid and I didn't feel it was fair to just shut everything down after seven months even if I knew the business model wouldn't work. Therefore I kept paying the server and data costs for a full 3 more years expecting users to move onto other apps but it just didn't happen! I regularly got emails from keen users who still used Windsock every day!

Unfortunately, the costs reached a point where I had to make a decision to either shut the server and app down completely or try and resurrect the business model to make it sustainable. Hence Windsock 3 is now using an in-app purchase subscription model with a host of new pro-level features. I know that is very frustrating for many of you. If it helps I kept the app version going well beyond its original 1 year lifetime, however, I hope you understand I had to make the change or kill the app completely.

Windsock 3 has a host of new features and data which I hope you'll try out and I would like to thank you for supporting Windsock over the years.

Does Windsock work in all of the USA? E.g. Hawaii and Alaska. How about Scotland?

Windsock uses a wide range of data sources, which are aggregated together statistically to provide the most accurate forecast possible for a given location. Whilst developing the application, hundreds of test points all over the world were used and Windsock has been developed to give excellent readings particularly in remote locations.

How accurate is the wind data?

Windsock uses data from a next generation forecast service that gives high-resolution readings every hour up to 7 days in advance. This is a paid-for service that uses multiple weather services such as local weather stations, satellites and even meteorological airport forecasts and feeds them into various weather models to generate highly accurate local forecasts for locations all over the world.

Which units of measurement are supported?

Windsock will display wind readings in kts, ft/s, mph, m/s, and kph. Temperature units can be displayed in degrees C and degrees F while the pressure can be displayed in hPA (millibars) and inHg. To configure this open the app to the main screen displaying all your sites. Tap on the Settings cog on the bottom left toolbar and then tap Units. You can then configure your default measurement unit.

Why is there a battery warning symbol on the readings?

This symbol displays in cold temperatures when Lithium Polymer batteries such as those used in GoPro cameras, RC planes and drones often have reduced performance. If this is a feature that doesn’t apply to your activity you can turn it off in the settings. To do this, open the app to the main screen displaying all your sites. Tap on the Settings cog on the bottom left toolbar and then toggle the Battery Warnings switch.
