The situation around weather apps really confuses me: my understanding is that most weather predictions come from massive networks of weather stations and very complicated and expensive simulation, both of which are publicly funded. This information must be available via some public API. Making an app is "just" providing an interface to this. I don't mean that front end design is easy (as demonstrated by a lot of badly designed weather apps), but it does mean that most apps should give you exactly the same information. With this in mind I just looked for a publicly funded app (so no adds, free) and ended up with Yr. Am I missing something here?
