Totally agreed on it being a marketing term, not a real prediction improvement - it's essentially the same as any other app in terms of "will it rain" / etc.

But they do a much better job of notifying about changes based on where I physically am, instead of for the city / region as a whole. Other weather apps I've used don't differentiate between "rain falling now 50 miles away" and "rain falling on my head", even though the radar map clearly gives them that info at a much finer level of detail.
