It works for me!

It took me a bit to figure out how to get it working but I fianlly got it! After you install it, go to your application folder and click on the emoji free icon. Once you do that, a little smiley face should appear in the upper right corner (near the battery life, wifi single, etc.) Then, to use, simply click the emoji you want (which copies it) and then paste it into your chat, text, etc. I only gave the app four stars because they are lacking in the variety of emoji... but, hey, it was free!
