Ive been looking for an app to show the GFAs for some time now, something about using AWWS while mobile and the amount of pages to load to see them makes the experience painful and unwanting. Luckily I ran into this app which has a very handy and useful way of viewing the GFAs, as well as the Radars for Canada. I would suggest and request if possible to get the rest of the weather available from AWWS (Nav Canada) such as the upper level winds, METARS, TAFS and even Echo Top Radar if possible. Even with what this app gives now, its well worth the price.
