Q: Can you use more than one emoji app?

All the emoji apps have been removed from the App Store because the Emoji keyboard is now accessible in all iPhones (since, I believe) iOS 5.

Settings>General>Keyboard>Keyboards>Add New Keyboard.

There is no need for a separate app.

Glad it helped.

Keep in mind that sending emoji in SMSs to non-iPhone users can give some very odd results up to and including completely garbled texts.

Don't know what app store you use, as there are hundreds in the US app store.

Sorry, I was specifically referring to the ones that activated the Emoji keyboard, which used to be required. I was not referring to ones that simply allow you to paste things in.
