It's on the cusp of greatness, as whimsical apps go. – Swiftmoji - Emoji Keyboard Review

The intuitive interface allowing text to morph into emoji is pretty cool, and I use it fairly regularly, if I happen to be communicating with close friends and family via iMessage; it collects dust if the person on the other end of the line is a business contact or casual acquaintance. The only thing that frustrates me in the course of its use is the sporadic and annoying game of "Keyboard Whack-a-Mole" I am forced to play more often than I consider acceptable. When I choose a keyboard, I expect to use it until I switch to another – not when some glitch dictates.
