SwiftKey, the popular keyboard app on Android has arrived to iPhone and iPad, unfortunately it only brings half of its capabilities notably the speedy typing method that consists of sliding finger across keyboard to string together words and the personalized predictive typing; only the latter comes to the iOS version. Furthermore unlike Android, Apple restricts third party software to modify the system soft keyboard; SwiftKey keyboard only works within SwiftKey note-taking app. You can save note to Evernote or manually use copy/paste the text to other app.
With that said and out of the way, SwiftKey Note is absolutely the fastest way to take notes using magical prediction technology, it intelligently autocorrects words and separate words as you type and offers next-word predictions based on the unique way you use words together. It gets smarter the more you use it, and adapts with you over time.
Notes can be store in Notebook for better organization or you probably just use it for typing scratchpad and copy/paste to other apps.
