If you have a Samsung smartphone and want an accurate weather forecast, Samsung Weather is an official app from Samsung that provides exactly that.
With this app, you can get an idea of the upcoming forecast for your current location with just a glance, seeing not only today's weather but the entire week's. You can also set up a widget on your screen so you check this information without needing to open any app.
One of the best aspects of Samsung Weather is that you can see updates on the weather at all times, specific to your current location, without having to change your location manually when you travel. You can also check the weather in other areas even if you're far away, giving you an idea of the weather in cities you plan on visiting or where your loved ones live.
