Bad design, half-good code.
It loads data, it refreshes it when opened (sometimes), it has city adding (although very bad design of this part) and deleting via long-tap. It has lots of room for easy improvement by, for example, replacing weather icons with something better or altering layout of components in layouts. I'd say it is NOT market-ready, as design is more of a technical draft than something finished.
Uses OpenWeatherMap API. Forecasts are for 5 days I think.
