Apple pencil stolen, can I track it ?

No. They didn't put GPS into it.

Nope

Wise move on your part. I also would not buy any small expensive item that can be lost. Good to know your limitations.

This does NOT look like an approved app from Apple and downloadable from the Apple OS App Store.

No one should trust that link you supplied in your post.

Beware.

Sorry but no because it dose not have a system like software or a chip to track it.
