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.

This is a great app, and a wonderful alternative to paying for RadarScope. The only things holding this app back, that I would like to see implemented, are 1) the ability to turn off the blue cloud surrounding the WSR, and 2) the ability to increase the width of the drawing tool, as the current pen width is just too narrow to be able to easily see. If these things are implemented, instant five stars.

Not bad for being Ad-free. I've been in and out of downloading weather radar apps. So far this app and Radar X are my goto's. I'm kinda the weather geek 🤓 when it comes to this. I'm not having any problems with the learning curve that gets thrown at you when you want specific information at a location. I also like the Area Forecast Discussions which analyzes the weather, in more detail, so you can understand what's taking place and why. Not bad for free.

Like a lot of other reviewers, I stumbled across this after PYKL3's development ended and that app stopped working. This is a solid effort that's really well put together for something that's free and open source! There's more information that you can shake a stick at, and plenty of customization (although it can always use more, like adjustable delays between animated frames, and things like that.) The only issues I have with it are the national radar map graphic is squished and can't be zoomed, so it's almost impossible to select radars from that particular image. (Radars can be selected by long-pressing on the actual radar window itself, though which is even more handy!) The other issue is that city/town names on the edge of the display tend to get all bunched up and unreadable. Animation is slow or doesn't render correctly on L2 data, but I see the author has offered a possible solution to that, so I'll update this if it fixes my problem there. So, that's it. A few tiny little issues but not enough to deduct any stars. The more I use it, and more I learn, the more I am impressed with the effort put into this app.
