I prefer the UI of darksky.net for both mobile and desktop despite it being the same data
I haven’t found one as nice, but windy works well, if not for a lack of localized default settings. I currently use weather bug, but I have simply lowered my expectations when it comes to weather apps.
I’ve been using Carrot and I like it, but I feel like it has way more customization than I want. There’s so many menu layers and display panels and options.
I’ve been using Carrot with Dark Sky data. I assume that they will switch to Apple Weather API.
