When George Mallory was asked why he wanted to climb Mount Everest, he famously replied, "Because it's there." I imagine a similar disposition possessed the developer of Wear Browser (better known for AIDE) when he shrugged his shoulders and said, "Well, I guess I'll put a browser on that watch." I say this because I can't think of a good reason anyone would do this. Still, it exists.
This app is completely free, so you don't have to spend any money to check out this betrayal of everything Wear stands for. It does seem like a neat little project from a development perspective, though. Wear doesn't support WebViews on its own, so Wear Browser implements Chromium on the watch. The list of project credits (seen below) is impressive, due mostly to Chromium. In seriousness, you might as well check it out if only to gawk at the weirdness.
