So far the best app I have found on tracking global data with radar function. It has two major radar data, precipitation and clouds. If it can provide more like winds and temperature radar as well it will be so great

Would like a wider area of coverage so I can see what weather is coming the next day.

I live on Kyushu south of Fukuoka, and the radar coverage is never complete around my town or within 100km in any direction. The app has potential to be nice, but as it stands right now, it is of very little use.
