The searching existing on-screen context / inserting relevant data is actually MUCH better on Android in the form of Now On Tap, which came out with Android M around this time last year - http://gizmodo.com/google-now-on-tap-hands-on-contextual-awe... . It has the added benefit of looking at what's on your screen to figure out what you want vs the new iOS keyboard where you have to click the G, then type in whatever you were interested in again.
This app is basically just trying to cram as much as they can into the keyboard, since they can't offer an option like Now On Tap on iOS due to Apple restrictions.
