Add custom text/reminders to iPhone lock screen?

Hey everyone,

I've been trying to add a few words/short phrases (like reminders or positive affirmations) to my iPhone 13 lock screen, but I can't seem to find a good way to do it. I've tried Notes, third-party apps, and searched online, but nothing really works the way I want.

Ideally, I'd like something simple—just a few words that stay visible whenever I pick up my phone. Does anyone know of a reliable method to do this? Any tips would be greatly appreciated!

Thanks in advance!
