If you love to send Emoji on your iPhone, you'll love the new option to send animated Emoji from your wrist. Although some users may find this a bit too much, you can choose to send animated thumbs up, thumbs down and other Apple Watch emoji. There is a smiley dace that can laugh, stick out it's tough and you can also use your finger to change the mood of the face.
If you send these to another Apple Watch user they are animated. If it is sent to a iPhone user it will include a image of it.
