I have heard good things about Dark Sky, but always pause before purchasing paid apps if there are other free apps out there that do the same thing. I've been using Yahoo! Weather on my phone for the past year or so and have been OK with it and the app seems to be OK on the Watch as well. But I heard it's "glance" is really good on the Watch. Is Dark Sky worth the money and is it that much better than the free weather apps out there? Thanks in advance.
