I turned my Android into a custom macro controller using a free app

I was looking to hook up my PC to a Stream Deck to make things easier. However, when I glanced at the price, I closed the tab and went back to fumbling with keyboard shortcuts. But being a technology geek, I started researching if there was something I could do with my smartphone and found something very interesting. The best part is that you don’t need dedicated hardware for this, as Android phones can replace expensive desk gadgets if you know which apps to use.
