I would LOVE if Samsung weather app handled the information natively within the app, keeping with the 'front page' aesthetic, instead of acting as a skin for the weather channel website.
Every item you click is nothing more than a link to the website, which in my humble opinion, is both ugly, and unintuitive.
The way things are, this doesn't feel like a Samsung first party app, but a skinned 3rd party app filled with API calls and hyperlinks.
The app needs to take its information from somewhere and for me the data is broadly accurate. I do agree though, I only ever try to use the widget as it is attractive and informative in its presentation. The website is lackluster at best.
