Most comprehensive weather app

Best weather app I've found so far. I use Wunderground's full website, but was underwhelmed by the Wundermap app. So happy they came up with this one, that has the most weather information at your fingertips of any weather app I have used. My only wish, as a pilot, is if it had aviation weather including winds aloft. If they had this, it would be every pilots dream weather app. The discussion tab is invaluable for overall picture of changing weather. This is a fantastic feature.

Update: would like aviation meter and taf with winds aloft, but in the discussion tab (which is hard to's in the daily forecast, far right icon) there is aviation discussion by NWS, where the discuss general trends and this is really helpful too.

They Finally Got It Right

This app has been around for a while, but I think it was recently acquired by a different group. Finally, they got it right! It shows both past and predicted future radar tracks up to 5 hours ahead. This is something I have checked out many weather apps to get and most do not provide the predicted future tracks for that far ahead. Living in an area prone to tornadoes and storms at times this is important to me.

It is definitely worth the $1.99 upgrade for a 12 month subscription to get the damm ads turned off. And since this guarantees a reasonable continuing revenue stream for the developer, they have an incentive to keep it supported and updated.

More useful info, well displayed

Most weather apps show barometric pressure; without indication whether it's rising or falling, it's not too useful, especially if you haven't memorized what normal pressure is. This app shows history graphs for pressure and a host of other parameters, so you can see how they are trending.
Other displays are readable and separated, so you can concentrate on hourly, daily, current, bulletins, or videos. Current also compares temperature with records and averages.
It's also fun during storms to get a phone alert almost simultaneously with a thunderclap!
I've loaded several weather apps, looking for The One, and this, along with Weather Underground, which Storm links to, is becoming my main source.
