Why does my ui have bad graphics on mobile?

Hello!

I am creating a loading screen for a game I am making with the UI Widget. I have been testing the game using the Unreal Remote 2 app. In my widget, I have some text that says “Loading”. The text, when tested on my iPhone 6S, looks ok. But when I run the game on my iPad Air 2 the text does not look great at all. Any help will be much appreciated.

I am going to attach two screenshots, one from my iPhone and one from my iPad.

Thank you!
