Not only is this the best rain prediction app that Ive ever used but it offers something that Ive never seen in any other weather app before.
First off, most weather apps will give you an hourly forecast, some will even give you a resolution of 15 minutes but thats about it. Rain aware has a resolution of 5 minutes and I have found it to be very accurate.
You might wonder what the big deal is. The big deal is that not only will it give you a chance of precipitation in 5 minute increments but it also tells you HOW SEVERE the rain will be in 5 minute increments. Ive not seen that offered by any other weather service, at least not to this degree of accuracy and ease of use. It is very easy to read and understand. At a glance you instantly know how heavy the rain is likely to be and how strong that estimation is (how confident the app is with its estimate).
I also love how you can tune the app to be very extremely sensitive if you are concerned about the lightest sprinkle, or not if you only care about substantial precipitation and dont want any false alarms. It does this by letting you adjust 3 key parameters, those parameters are precipitation intensity, confidence, and clutter filtering.
Last summer during a 4 day period every single tv weather station was warning us of severe thunderstorms, heavy rain, microbursts, and tornadoes. Rain aware predicted very light rain and that is what we got, light rain. It was more accurate than the combined predictions of 3 local weather channels, and the two weather websites that I happened to check.
RAIN AWARE IS HIGHLY RECOMMENDED AND IS DEFINITELY WORTH THE MONEY.
