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.
