Updated for 2018 - better than ever - Rainfall is a new way to display and analyze NEXRAD Level III radar data provided for the United States by the National Weather Service. This app was custom written, including the NEXRAD Level III processing engine, by someone living with and overcoming his life story with Autism.

The application features the ability to view and display NEXRAD Level III data including Base Reflectivity, One Hour Rainfall, and Storm Total Rainfall currently with more features planned already.

By your purchase your supporting my health and high functioning Autism. I started writing this App before being placed in emergency surgery with no local support system and never had to chance to publish it until today.

If you have any questions you can e-mail me personally to get help - features, bug reports, or just to say hello (even a message of personal support) to
