Very good app



What is the point?

Why would I need your location service to tell me the weather in nearby places? If I want to know the weather in a specific place I can easily look it up in full detail online.

The "forecasts" in this app are just temperature range & a sunny/cloudy/rain icon with zero detail, and seem to be available only for major cities in Asia. Shorter-term forecasts can be found for certain European cities, but anything in North America shows only today's weather. Not very "worldly" at all.

For me, the one positive attribute about this app is it got me looking for another, better world weather app and found Weather+ Free, which is years ahead of this joke of an app in every aspect.



Good app

Don't know why some people always give offensive comments to free apps. Remember u dont need to pay. Shame on u and empathic on u to be an ALWAYS negative person - must hv an unhappy life.
