One of my favorite applications for Apple products is Gaucho Soft's Seasonality, which I have been using for years. It is a great weather monitoring application, with the particularly nifty animation of particles indicating wind temperature, direction, and velocity.
The iOS version is Seasonality Go, which is well worth buying if you monitor multiple weather locations. If you want to see your locations' maps in the local languages' scripts—e.g., see Tokushima City in Japan as 徳島市—the app itself does not (currently) offer a language display setting. You must flip the following setting for Maps, which you find by going to:
Settings : Maps : Always in English and switching it off, as shown below. Turning it on (green) leaves you with the Roman alphabet.
Now we can see the weather in the language where it's happening.
