About this app

wX is a free, no-ads, and open-source ( GNU GPLv3 ) advanced weather application that is geared towards storm chasers, meteorologists, and weather enthusiasts. NWS ( National Weather Service ) data is optimized for mobile format and provided for divisions not normally covered together in the mobile space: SPC, WPC, NHC, OPC, etc. Level 3 and Level 2 Nexrad radar ( single, dual, quad pane ) are provided and displayed using the mobile variant of OpenGL. This weather app is not affiliated with NOAA or the National Weather Service.

If you *only* need current conditions and your local 7 day forecast then this app is probably more then you need although it will easily provide those 2 things as well. If you are looking for wasted screen real estate or fancy graphics this app is not for you. Given the depth of information covered there is a steep learning curve if you seek to use the program in it's entirety, help information is available and touched on below. Common weather acronyms are used throughout so you should be familiar with those as well. Currently United States locations are supported.

HELP is available from the main menu and by tapping on any text in the settings activities.

Unbelievable app, coming from a semi-pro meteorology hobbyist This is something I've been looking for. It's generally speaking a collection of publicly available data but it's concisely laid out in one place instead of managing 50+ different pages. The widgets and radar features are very helpful. Only feature request would be separate notification channels for each type of product, like one for US TOR, one for SPC Watch, etc. so different sounds can be set. Thank you for creating this for us!!!

Probably the best app out there. It displays pretty much any NOAA map or chart out there. This app is very useful while out chasing! My one complaint is the UI - something about it just makes me want to use other apps (which don't have as much data) like radaromega or radarscope (I'm not entirely sure what it is). Other than that, instant 5 stars.

I've looked everywhere, and I mean everywhere, for a weather app that sends me ALL tornado alerts across the US and this is the only one that does it. Every other app has location based alerts. I've used this app for years and I love it. If you want any kind of data about the weather, this app has it. The fact that it's free still blows my mind.
