Trapped by an app?!

*Fixed! Clicked the settings in the top left corner of the app and found a Quit button*
After downloading this free app, I was dissatisfied by a lack of popular emojis - such as most of the hearts. Naturally, I downloaded a new emoji app and went to delete this one but… YOU CAN NOT DELETE IT! There is no way to quit the app, therefore no way to delete it. I have no need for two emoji apps hogging my precious limited storage, what should I do?
