How to remove Apple stick from the window of my car

Do you mean Apple Sticker?

find edge and peel, if that doesn't work:

a) window cleaner and rag

b) utility knife

or

c) hammer

As Jimmy said, find the edge and peel, or use a knife and scrape., wet it (well) with soapy water.

Goo Gone will (with a little elbow grease) get rid of pretty much everything.

goo gone is what janitors use to take permanent marker off bathroom stalls.

it seriously will take anything off of anything including your skin and you will thin out your brain cell herd if you use it indoors, but yeah, it works!

I've never had a problem with it on my skin. Of course, I don't smear it on with my hands! 😉 And, of course, always use in a well-ventilated area.

For stickers made of paper, peanut butter works quite well. It's better than vegetable oil because you can smear it on an let it sit.

its a hum-dinger of an aftershave. In fact I just use it to get rid of stubble or if I forget to shave for six months.

@OP the stickers generally come off windows by peeling slowly.

Zippo lighter fluid also does the trick (any brand will do) - with smart shopping, very likely much cheaper than Goo-B-Gone
