Not Real Time
The description of the app states that it gives you real time wind data. It does not. It updates when you start the software and then never again until you quit and restart. It also does not let you choose a location so it must use location services which, in my case, is close by but many miles from where the I live. Both of these issues are really bad considering what the software is supposed to be doing for you! Come on developers. This can not be hard to fix! It is certainly not worth $2 otherwise!
