Viticci has some nice iOS 8 features for you, this one is particularly cool:
Travel time was previously exclusive to OS X Mavericks, and it’ll come to iOS 8 through (optional) notifications that’ll suggest you the best time to leave for your next calendar event. It’s not clear whether iOS 8 users will also be able to turn on travel time and get inline Maps previews when creating new events in Calendar, but notifications are a good start.
That’s awesome. So too is the emergency ID card, but it’s pretty convoluted to get to right now.
