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.

Extremely detailed!!! Great for those that have and interest in meteorology beyond the normal weather app. Interface is not easy to learn and will take time to get use to. I started out setting up location points for seven day forecasts and exploring the menu options from there. EXTRAORDINARY DEPTH!!!

Intended for USA only!! This is one of 3 top weather apps which reformat the wonderful NWS mobile site to be more legible. "Wx" is my top choice, though it's a little hard to learn. Fonts can be a bit small. Easy access to SPC graphics. "NWS Now" is best for usability and legibility, but only available on the Amazon app store. "National Weather Service", by Cynosure on the Galaxy store, is getting out of date and some of the graphics simply won't load.

This app is an excellent resource of information for weather enthusiasts. I've chatted with the developer via email about his Linux version of the app and my experiences, and he's extremely respectful and nice. My only current suggestion for the app at this time is to show the most recent outlooks and tiles when clicking the SPC and MISC tabs at the top of the app, rather than static-outdated images.
