I have an iOS shortcut that anyone can use to do something similar. Install it, name it "What's Overhead", and then you can say "Siri, what's overhead?" and then Siri will speak details on whatever aircraft is closest to you.

I use it when driving, or via my watch if I hear an unusual plane or helicopter and don't want to pull out my phone.
