I was lamenting the hassle of opening a browser and navigating to a website to access metars and tafs, so decided to see if there was a "widget" that would display the information on my home screen. Of course there is. Anyway, I found an app called "Windsock" which very simply displays metars and tafs for your selected airports. It also includes a widget that displays the information for one airport on your home screen and acts as a link to open the app. I wish I had found this years ago and thought some here might find it helpful. It's free with an ad on the bottom, but I think I'm going to cough up the $1.50 the developer is asking for the "pro" version because it's so handy.
