hyperlocal is a joke, sorry to say it. Just because you can downscale your grid to a very small number doesnt mean good data. It just means you can do statistics and mathy stuff to interpolate. Everyone forecasts better in stable times such as a strong high pressure ridge. The tricky part is the edge areas between air masses, the transition zones. This is where all the juicy weather actually happens and it is the hardest to model

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.
