DO NOT PURCHASE THIS WIDGET: it is only present on Google Play to allow already customers to update it.
Previous version queried Weather Google but this service is discontinued by Google. This version queries WeatherUnderground, but has a limitation of the number of queries.
Updating to this version, customers who purchased the widget will still be able to use it, but no new clients are expected and that is the reason the price is ridiculously high.
DO NOT PURCHASE THIS WIDGET.
