GNW:Basic displays up to date radiation measurements.

First, a short disclaimer. GNW is not a game where you nuke countries. When you run the app, look for your current location. The app searches the nearest sensor and shows whatever it has to show. The nearest sensor usually is the nearest nuclear power plant, so be prepared to remind how close it is.

Mundane people would find quite difficult to understand what the numbers mean, so there's a understandable explanation of each measure and what are the harmless limits. You can access to that sensor's graphics and location, in case you want to check that things aren't getting worse.

Maybe the result is somewhat paranoid, because the dial gauge marks to yellowish green so I don't know if it's better to bury myself underground or continue as if nothing was happening and I haven't ever downloaded Global Nuclear Watch. Anyway, no matter how you look at it, this app also aims to raise awareness about how exposed we are to nuclear radiation and how close we are to a potential source of trouble.

In the meanwhile, a proper app if you take current times into consideration, and a smart use for our beloved Android devices.

    The only reliable app of it's kind afaik. If you realy want to track some places, I recommend using the pro version because you can place widgets on your homescreen. But the free version does it's job too!

    The app is pretty nice, but im just not fond of the font and layout. Giving it the blue dark holo theme (with stock android) would be spot on for my taste. Also, care to add some radiation meters in finland, especially at the nuclear power plants like olkiluoto?

    Very limited selection of locations and most of them are displaying extremely outdated data. Only 2 locations (neither in my country) had results from this year. Most of the locations the last recorded data sample was back in 2011. Not sure what good two year old data does anyone.
