The Canadian VTA and VNC maps are absolutely brilliant. This app is amazingly simple to use, yet exceptionally powerful. As an early student, it makes my life in the cockpit that much easier. However, the scratchpad needs a serious overhaul; there is no erase, and there is only 1 page of notes, leading to a horrible mess when you have plenty to write. The writing is imprecise, and it seems to average two touches, leading to weird lines if a finger touches the edges on another part of the screen. Otherwise, great app. Well worth the yearly subscription price.
