Some forecaster app. You can add city by pressing a button and deleting by long press on item in list.
All data is stored in db, when you "open a city", firslty you see a data from db, then, data is loaded and db is updated. English city names are supported only, you can type incorrect name of the city and API will try to recognize what did you mean, and real city name will be added to citylist after first update.
