One of the biggest new iOS 12 features is only coming to the iPhone X. Apple now offers Memoji, which allows you to turn yourself into an emoji that becomes an Animoji.
This isn't an automated process like Samsung, you use a wide range of features in the Memoji app to create your custom Memoji that looks exactly like you using tons of characteristics. This is basically an Apple Bitmoji clone that you can use throughout a wide range of Apple apps.
You can control your Memoji and send it to others in Messages, just like you can with Animoji. You can control winking and your tongue, just like with the Animoji upgrades.
You can also use your Animoji in photos for Messages in addition to filters and effects so that you can spice up your messages. Your Memoji can also appear in FaceTime video calls right on your head.
