Universal Copy is an app to copy text snippets from any app you're using. This means you can copy text even if the app you're in at that moment (Instagram, Facebook, Twitter, etc.) doesn't let you do it by default.
All you have to do to use Universal Copy is open your notifications bar, tap the button for the app, and then select the lines of text you want to add to the clipboard. That's it. So easy to copy any snippet.
Universal Copy is a very useful app in certain situations. With it installed, no app can stop you from copying text and adding it to your clipboard.
