Hello! I’ve been wondering for quite a while now, how does the weather app seems to know the wind speed, temperature and all the other things about basicly any given location, and seemingly pretty accurately. I understand that big cities might have certain sensors, and whatnot, but what about small villages, or places in the middle of nowhere? How does it know all that?

Because weather systems are huge. Meteorologists measure and calculate how the entire weather systems move. A forecast is a series of samples taken from a specific location within the big weather model as it evolves. If a powerful cold front 1000 miles wide is moving across an area, we can predict that both the big cities and the middle-of-nowheres it hits will get heavy rain and thunderstorms.
