Most pilots are weather geeks, either by disposition or training, and that means a good weather app can be particularly helpful or even fun. The big electronic flight bag apps like ForeFlight and Garmin Pilot do a great job of consolidating the key weather maps and forecasts, but there is a role for non-aviation apps. A great example is Ventusky, a $3.99 app that beautifully displays maps of wind, clouds, and more.
