Additionally, I really dislike the Apple Weather dataviz for the day's trends. This time of year, the my local weather can wildly change from early morning to late afternoon, and I want to plan what to wear. I could glance quickly at Dark Sky and see the trend almost instantly. Apple Weather requires this awkward tap and drag gesture to see actual temperature values through the day.
Apple weather puts all sorts of weather data at the same level, despite the utility being wildly different. I need to know the temperature trend for the day, or rain chance. Wind speed isn't very useful to me day to day, yet they are at the same "level" of UI access. It doesn't feel very driven by user needs, but perhaps there are a lot more sailors using the app than I realize.
