FONT & APPEARANCE
If you struggle to read small text, bump up the size by going to Settings > Display & Brightness, selecting Text Size, and dragging the slider to the right. You can also improve readability by making your text bold. Go to Settings > General > Accessibility, and then toggle Bold Text On. Once you've restarted your iPhone, all of the words on your device will show up thicker and darker. You can also invert the colors on your iDevice in Accessibility by toggling on Invert Colors. It's a fun look to give a try, and you can easily turn it off with a triple-click.
