If the bright light of your iPhone or iPad display is bothering your eyes, Apple's iOS and iPadOS support system-wide dark mode. Here's how to turn it on.
With iOS 18, Apple is finally opening up the iPhone home screen. You still have to adhere to a grid, but other than that, you can freely place app icons, remove text labels, get dark mode icons ...
The iOS 13 developer betas are out now, which hopefully leaves them some time to get their own apps kitted up with dark mode when iOS 13 fully rolls out this fall.
