A feature that was hidden in iOS 7 is now front and center in iOS 7.1. Now, when you open the Calendar app in month view, you can touch a button at the top to see your daily list of appointments, meetings, and birthdays without having to navigate to a different screen.
Siri received a few feature enhancements that are not apparent on this screenshot, but worthy of note. You can now hold down the Home button then let go when you are done talking. Before, Siri would automatically recognize when you stopped talking, but in loud environments, would sometimes pick up words you didn't want it to. This change makes your questions more precise.
On the left is iOS 7.0, and on the right is iOS 7.1. It's not a huge difference but a helpful one. You'll notice that the caps key is different and more readable in iOS 7.1, along with the backspace key on the right. Also, though it's hard to tell, the letters themselves are a bit bolder in iOS 7.1.
On the left is iOS 7.0, and on the right is iOS 7.1. Here you can see the addition of today's priorities (with the new button at the top) in the month view in iOS 7.1. You'll also notice that 7.1 uses a bit more gray (in the background) to contrast with all the white.
On the left is iOS 7.0, and on the right is iOS 7.1. The dial pad in iOS 7.1 even received some small tweaks with a slightly darker background and the smaller call icon instead of the big green "Call" button.
Touch the colorful icon in the lower right of the previous slide to bring up nine filters you can apply to your photo. There are some decent selections here, but nothing as drastic as you find in third-party photo editors.
The weather app now looks a lot like the standalone Yahoo Weather, which makes sense because Yahoo powers the weather app in iOS 7. It looks great, but you don't get as much information as you do with the standalone app.
