From what I've heard, it sounds like it's not nearly as good or simple an experience as DarkSky was. But as an Android user I wouldn't know, DarkSky was just killed by Apple for everyone but Apple customers when they merged it in.

As an Android user you can absolutely pay for access to dark sky's api.

I think I can pay for access to the Apple Weather api, which is neither the DarkSky api, nor the DarkSky app that was killed by Apple.
