The title maybe it's not describing the best what I'm looking for so let me explain.
I'm using the Sentinel by Samourai Wallet for a watch only addresses. It's a perfect address watcher except they don't have a notification option if there are any incoming/outgoing transactions.

Is there any app where you can set up a notification when you receive/send funds?

This can be a very useful tool to watch over your bitcoin. If someone steal your coins and you get a notification, it's already too late but still you know that something is wrong and can prevent the hacker to make more damage.
