Fresh Air is the first weather app I've used that I actually wanted to look at for more than a few seconds.
That's because Fresh Air turns the weather and upcoming forecast into something you can dive into and explore, rather than the traditional static list of temperatures and conditions accompanied by a weather animation in the background.
The first thing you notice about Fresh Air is its minute-by-minute weather graph, a stylish and minimal graph that you can play around with to explore how the weather will be over the next seven days. Don't get me wrong, the minimalist design aesthetic extends to the rest of the app too, but the graph is too interesting to ignore; it practically begs you to slowly swipe forward to see how the temperature will dip in the evening, rise in the morning, and plateau in the afternoon.
You can even track things like sunrise and sunset, and the app's background brightens and dims accordingly, allowing you to pay less attention to the specific time as you scroll.
Perhaps I just prefer visuals to mere numbers, but there's something about being able to track the weather's trend on a minute-by-minute basis that makes checking if you'll need a heavier coat for the walk home a lot easier.
Beyond being fun to explore, Fresh Air also connects to your calendar to give you forecasts for your upcoming appointments. Once synced up, you can easily see whether or not it's supposed to rain during your lunch meeting, and it's designed to save you the trouble of manually look up the conditions.
Fresh Air also tracks quite a bit: There's data on wind, humidity, precipitation chances, severe weather warnings, sunrise and sunset, and a handy "feels like" temperature. If you don't have time to jump into the app itself, you can always get a tidy summary with the widget by pulling down the Notification Center on your iPhone's lock screen.
