SwiftKey is one of a number of replacement keyboards for iOS 8, and it has two standout features: predictive text (which offers word suggestions based on your typing) and the ability to swipe letters on the keyboard in lieu of typing. The swipe-to-type feature, which SwiftKey calls "Flow," is similar to what you'll find on the Swype keyboard, but the predictive text feature is unique to SwiftKey.

What may make people a bit hesitant about Swiftkey is that its predictive text feature requires Internet access in order to work. Other keyboards seem to be able to do this without the cloud access, but the cloud access does seem to give the app a quicker learning curve. Also, iOS doesn't let you use third party keyboards to enter passwords, so major privacy concerns are not an issue.

Swiftkey is available for the iPad and the iPhone, but switching between the character and number keyboards often crashes on my iPad, so I would skip that iteration altogether. (The iPad version also lacks the swipe typing, so it's not getting you much anyway.)

What's Good: Good interface, learns your words quickly.

What Sucks: Bugs on the iPad, requires Internet access and a SwiftKey account.

Buy it?: If you're looking for quicker input, but don't mind the cloud account and data sharing, pick up SwiftKey for free on the App Store.
