I am many things, but never the same. I fall from the sky and be eaten any time of day. Also, I am a unique five-sided work of art, and always late. What am I????

Fuzzy on the outside, Juicy within, If you hate me with skin, You can eat me from a tin.

I travel far without a sound, Through air or space I move around. I tell you when to stop or go, or share a message you should know.

I am the field that contains an answer. I am an island with gaps on either end. It takes many of me to write an essay, unless you're talking about the app.
