How do you tell what code certain apps are made of?

Question

I’d like to know what code certain apps are made of and wondered if there is a way to see?

Answer 1

What app are you trying to find information on?

Answer 2

In most cases, the easiest way is to try to find it online. In a lot cases, the developers will post what language was used. It probably won’t be very easy to find, but it should at least work.

Answer 3

I looked to see what it was but didn’t go past the first page so that’s probably my mistake thanks.

Answer 4

It called Star Wars galaxy of heroes. I enjoy the game a lot and want to figure out how it was done.
