After the shutdown of Dark Sky, I switched to Carrot, which added a layout that mimics Dark Sky's design (the layout option is called "Anubis" in the Carrot app). I've found it to be a largely seamless replacement.
Agree, though there's still something about Carrot's underlying design language that is less subtle and refined. It's a very, very minor complaint given the effort Carrot clearly made (and their evident appreciation for a competitor that did things better for many users' preferences), but there's some weird information processing lag I still experience with Carrot because I'm fighting the UI even though it looks almost identical to DS. In the end, I actually enjoy the experience because (a) it's so minor and (b) it gives me an opportunity to play with how my own brain perceives the universe. So that's fun.
