title: How to create a React Native floating app that checks the user screen?
body: <p>Im not asking for code, Im just asking for a way to follow.</p>
  <p>I play this game called Clash Royale where the player plays a card and that card &quot;summons&quot; a character.</p>
  <p>I want to create a react native app that is floating like a sidebar and that tracks the cards that have been played.</p>
  <p>I know that I need to create a logic to check for specific pixels but i wasnt able to find how to make the app to be floating and to check the user screen at the same time.</p>
  <p>Can someone give me a tip, please?</p>
