Tried Avia first, wouldn't let me search for airports using ICAO identifiers. But would find local airports. Spent the $3.75 to unlock all of the features, still couldn't search for what I was looking for. This is perfect, with the $.99 to upgrade to Pro for the color coded precipitation. If you want an easy to use, no frills way of checking METAR/TAF info, this is for you.
